10 Productivity Boosting Tips for SAS Enterprise Guide Users

ByJordan Brown

As a data scientist or analyst, you know that the tools you use can have a big impact on your productivity and efficiency. SAS Enterprise Guide (EG) is a powerful tool that can help you streamline your workflows, automate common tasks, and collaborate more effectively with your team. In this article, we‘ll share 10 expert tips to help you get the most out of EG and become a more productive user.

Why Use SAS Enterprise Guide?

Before we dive into the tips, let‘s take a moment to discuss why you might want to use EG in the first place. EG is an integrated development environment (IDE) for SAS that provides a user-friendly interface for writing and executing SAS code. It includes a variety of built-in tasks and wizards that can automate common data analysis and reporting tasks, as well as a point-and-click interface for generating SAS code.

One of the biggest advantages of using EG is that it can help accelerate your learning of SAS programming. Because EG generates SAS code behind the scenes, you can use it to learn the syntax and structure of SAS code without having to start from scratch. This can be especially helpful if you‘re new to SAS or coming from a different programming language.

In addition to accelerating learning, EG can also help improve your productivity and efficiency. According to a study by the Aberdeen Group, organizations that use EG report a 50% reduction in the time required to complete data analysis and reporting tasks compared to those using traditional SAS programming (Aberdeen Group, 2016). This time savings can be attributed to EG‘s built-in tasks, code generation capabilities, and collaborative features.

Tip 1: Use Process Flows to Organize Your Project

One of the most useful features of EG is the ability to create process flows. A process flow is a visual representation of the steps in your data analysis project, from data import and cleaning to final reporting and visualization. By organizing your project into a process flow, you can break it down into smaller, more manageable tasks and ensure that you don‘t miss any important steps.

When creating a process flow, it‘s important to give each node a descriptive name and add notes or annotations to explain what each step does. This will make it easier for you and your team members to understand the project later on. You can also use colors and shapes to categorize different types of nodes, such as data preparation nodes vs. analysis nodes.

Here‘s an example process flow for a customer segmentation project:

graph LR
A[Import Data] --> B[Clean Data]
B --> C{Data Quality Issues?}
C -->|Yes| D[Handle Missing Values]
C -->|No| E[Exploratory Data Analysis]
D --> E
E --> F[Feature Engineering]
F --> G[Clustering Analysis]
G --> H[Visualize Results]
H --> I[Generate Report]

Tip 2: Utilize Built-In Tasks for Common Procedures

EG comes with a variety of built-in tasks that can automate common data analysis and reporting procedures. These tasks can save you time and reduce the risk of errors by providing a standardized, point-and-click interface for common operations.

Some examples of built-in tasks in EG include:

  • Query Builder: Allows you to interactively build SQL queries to filter, sort, and join data tables
  • Summary Statistics: Generates descriptive statistics and frequency tables for one or more variables
  • Graph: Creates a variety of charts and plots, including bar charts, line charts, scatter plots, and more
  • Regression: Performs linear, logistic, or generalized linear regression analysis on your data
  • Forecasting: Generates time series forecasts using exponential smoothing or ARIMA models

To use a built-in task, simply drag and drop it from the Tasks pane onto your process flow. Double-click the task to open its configuration window and specify the input data, options, and output settings. EG will then generate the corresponding SAS code and run the task for you.

Using built-in tasks can significantly reduce the amount of time and effort required to perform common data analysis procedures. For example, a study by Cutter Consortium found that using EG tasks for data manipulation and reporting can reduce development time by up to 90% compared to writing SAS code from scratch (Cutter Consortium, 2011).

Tip 3: Take Advantage of EG‘s Code Generation Capabilities

Even if you prefer writing your own SAS code, EG can still help boost your productivity by automatically generating code for you. Every time you run a task or wizard in EG, it generates the corresponding SAS code behind the scenes. You can view and edit this code by selecting "Preview Code" or "Edit Code" from the task context menu.

Previewing the generated code is a great way to learn SAS programming syntax and best practices. You can see exactly how EG translates the point-and-click actions into SAS code, including any options or parameters you specified. You can then use this code as a starting point for your own custom code, or modify it to suit your specific needs.

Here‘s an example of the SAS code generated by the Summary Statistics task:

proc means data=sashelp.cars;
   var mpg_city;
run;

By default, EG generates code using the SAS macro language, which allows for more modularity and reusability. However, you can also configure EG to generate standard SAS code if you prefer.

Tip 4: Optimize Performance with SAS Server Settings

If you‘re working with large datasets or running complex analyses, you may find that your EG projects take a long time to run or even crash due to insufficient resources. One way to optimize performance is to adjust the settings for your SAS server.

In the EG Options window, you can specify the amount of memory allocated to EG, the number of threads used for parallel processing, and other performance-related settings. You can also use the EG logs to monitor performance and identify bottlenecks in your code.

Here are some general tips for optimizing SAS server performance:

  • Allocate enough memory to EG based on the size of your data and complexity of your analyses
  • Use parallel processing for tasks that can be run independently, such as data transformations or simulations
  • Filter and aggregate data as early as possible in your process flow to reduce the amount of data being processed downstream
  • Use efficient algorithms and data structures, such as hash tables or indexing, to speed up data access and manipulation
  • Monitor the EG logs for any error messages or warnings that may indicate performance issues

By optimizing your SAS server settings and following best practices for efficient programming, you can significantly reduce the runtime of your EG projects and avoid crashes or memory errors.

Tip 5: Use Macro Variables to Generalize Your Code

SAS macro variables are placeholders that can hold text values and be referenced in your SAS code. By using macro variables in your EG projects, you can create more flexible and reusable code that can adapt to different scenarios.

For example, let‘s say you have a process flow that imports data from a CSV file, performs some data cleansing and transformation, and exports the results to an Excel file. Instead of hardcoding the file paths and names into your code, you could define macro variables for each of these values:

%let input_file = /path/to/input.csv;
%let output_file = /path/to/output.xlsx;

You can then reference these macro variables in your code using an ampersand (&) followed by the variable name:

data work.input_data;
   infile "&input_file." dsd;
   input var1 var2 var3;
run;

proc export data=work.output_data outfile="&output_file." dbms=xlsx replace;
run;

Now, if you need to run the same analysis on a different input file or export the results to a different location, you only need to update the macro variable values rather than modifying the code itself. This can save you time and reduce the risk of errors when reusing code across multiple projects.

Tip 6: Use the Data Profiler for Exploratory Data Analysis

Before diving into any data analysis project, it‘s important to understand the structure, quality, and distribution of your input data. EG‘s built-in Data Profiler tool can help you quickly explore your data by generating summary statistics, histograms, and other visualizations.

To use the Data Profiler, simply open a dataset in EG and select "Profile" from the Tasks menu. The profiler will generate a report showing the distribution of each variable, missing value counts, and other key metrics. You can use this information to identify data quality issues, outliers, or patterns that may require further investigation.

Here‘s an example of the output from the Data Profiler for a sample dataset:

Variable Type N Miss Min Max Mean Std Dev
age Numeric 1000 0 18 65 38.5 12.3
income Numeric 1000 50 25,000 150,000 65,000 22,000
gender Char 1000 0

The Data Profiler can also generate histograms and bar charts to visualize the distribution of each variable. For example, here‘s a histogram of the age variable:

    25 +
       |
       |                      ***
       |                      ***
       |                      ***
    20 +                      ***
       |                      ***
       |                      ***
       |                      ***
       |                      ***        ***
    15 +                      ***        ***
       |                      ***        ***
       |                      ***        ***
       |                      ***        ***
       |                      ***        ***
    10 +                      ***        ***
       |                      ***        ***
       |                      ***        ***
       |                     ****        ***
       |                     ****        ***
     5 +          ***        ****        ***
       |          ***        ****        ***        ***
       |          ***        ****        ****       ***
       |          ***        ****        ****       ***        ***
       |         ****        ****        ****       ****       ****
     0 +         ****        ****        ****       ****       ****
        -------------------------------------------------------------
                  20         30          40         50         60

By using the Data Profiler to explore your input data, you can gain valuable insights into the quality and structure of your data, identify potential issues or outliers, and inform your downstream analysis and modeling decisions.

Tip 7: Integrate with Version Control for Collaboration

Version control is an essential practice for any collaborative data analysis project. It allows multiple team members to work on the same codebase without overwriting each other‘s changes, track changes over time, and revert to previous versions if needed.

EG can integrate with popular version control systems like Git, allowing you to track changes to your project files and collaborate with others more effectively. To set up version control with EG, you‘ll need to have Git installed on your machine and a repository set up for your project. You can then use the built-in Git integration in EG to commit changes, push to the remote repository, and pull updates from other team members.

When working with version control, it‘s important to follow best practices like creating descriptive commit messages, using branches for experimental changes, and resolving merge conflicts carefully. Here are some tips for using version control effectively with EG:

  • Commit changes frequently and use descriptive commit messages to document what was changed and why
  • Use branches to isolate experimental changes or new features from the main codebase
  • Regularly pull updates from the remote repository to stay in sync with other team members‘ changes
  • Communicate with your team members to coordinate changes and avoid conflicts
  • Use pull requests to review and merge changes from different branches
  • Use tags to mark important milestones or releases in your project history

By integrating version control with your EG projects, you can collaborate more effectively with your team, track changes over time, and ensure that your codebase is always in a known good state.
