What Is the Advanced SAS Certification?

The Advanced SAS Certification is an advanced-level credential designed for professionals who already have a solid foundation in SAS programming and data analysis. The exam tests your ability to apply complex SAS techniques in real-world scenarios, covering areas such as statistical analysis, macro programming, data manipulation, and reporting.

Achieving this certification not only enhances your professional reputation but also increases your chances of landing better job opportunities, as it validates your ability to tackle complex data analysis tasks.

Key Topics Covered in the Advanced SAS Certification Exam

The Advanced SAS Certification exam is divided into several sections, each focusing on different aspects of SAS programming. The following are some of the key topics you will need to master for the exam:

1. Data Manipulation and Transformation

This section assesses your ability to handle complex data manipulation tasks. As a SAS professional, you must be proficient in transforming raw data into a usable format. You will need to demonstrate your ability to:

Merge and Concatenate Datasets: You should be able to merge multiple datasets using different methods such as MERGE, UPDATE, SET, and SQL JOIN.
Handling Missing Data: Identifying, handling, and imputing missing data is crucial in any dataset. You will be tested on techniques to deal with missing values using functions like COALESCE, IF-THEN, and CASE statements.
Creating New Variables: A major part of data transformation involves creating new variables based on existing data. You’ll need to master various methods of creating variables using ARRAY and DO loops.
Efficient Sorting and Indexing: Understanding how to sort large datasets efficiently and create indexes for faster retrieval is a vital part of data manipulation.

2. Advanced Statistical Techniques

This section covers your ability to apply advanced statistical methods for data analysis. Topics you need to be familiar with include:

Regression Analysis: You will need to be comfortable with performing linear regression and logistic regression using SAS procedures like PROC REG, PROC GLM, and PROC LOGISTIC.
Analysis of Variance (ANOVA): This involves understanding how to use SAS procedures to conduct ANOVA, including one-way and two-way analysis, and interpreting the results.
Multivariate Analysis: Familiarity with multivariate techniques, including factor analysis and principal component analysis, is essential. You’ll need to be able to use procedures like PROC FACTOR and PROC PRINCOMP.
Survival Analysis: You should understand how to conduct survival analysis using procedures like PROC LIFETEST and PROC PHREG.
Mixed Models: Using PROC MIXED to perform analyses for data that are grouped or correlated is another important area.

3. Macro Programming

Macro programming in SAS allows you to automate tasks, write reusable code, and manage complex workflows. This section evaluates your ability to:

Write Efficient Macros: Writing macros to automate repetitive tasks is key for improving productivity. You need to master macro functions and macro variables.
Debugging Macros: Knowing how to troubleshoot errors in macro programs and optimize their performance is critical for this exam.
Advanced Macro Techniques: This includes creating dynamic code using macro variables, working with macro functions, and using macro quoting functions to handle special characters.

4. SAS Procedures for Advanced Analytics

Advanced SAS certification tests your knowledge of SAS procedures, which are used to perform statistical analysis, data management, and reporting. Topics covered here include:

PROC SQL: This is a critical skill, as PROC SQL is used for performing database operations, including data manipulation and querying within SAS.
PROC REPORT and PROC TABULATE: Both procedures are widely used for creating detailed and customized reports. You will need to be able to apply these procedures effectively for complex reporting tasks.
PROC SURVEY: Understanding how to analyze complex survey data using PROC SURVEY procedures, including weighted data analysis, is important for the exam.
PROC TRANSPOSE: This procedure helps you pivot or restructure data, which is often needed in data transformation tasks.

5. Performance Optimization

Performance optimization is a crucial part of the exam, especially when working with large datasets. The Advanced SAS Certification exam tests your ability to:

Optimize Code for Speed and Memory: Writing efficient code to handle large datasets and reduce execution time is critical in SAS programming. This includes using indexing, efficient looping structures, and optimizing sorting techniques.
Data Set Indexing: Creating indexes to speed up data retrieval processes is another important concept.
Efficient Data Storage: You must understand how to manage large data sets and store them in formats that are efficient for both processing and retrieval.

6. ODS and Reporting

Reporting is an important aspect of the Advanced SAS exam. This section tests your ability to:

Customize Reports Using ODS: The Output Delivery System (ODS) is a powerful feature for creating customized reports in various formats, including PDF, HTML, and RTF.
Create Graphs and Visualizations: Understanding how to create high-quality graphs and charts using ODS Graphics is necessary for presenting data in an easy-to-understand format.
Use PROC REPORT and PROC TABULATE for Reporting: These procedures allow you to generate and format detailed reports, which are critical for delivering results in a professional setting.
