About this Course

Data Science with SAS has always been an add-on skill for Data Scientists who wants familiarity not only with SQL, Python and R but also with the Statistical Analysis System which is commonly abbreviated as SAS. Though it is less likely used as a primary analytical tool in the field of Data Science, but SAS provides a number of products to its users which can change the perception of it is used as a primary tool rather than an add on skill by the experts. Some of these include Asset Performance Analytics, Analytics for IoT, Business Rules Manager, Customer Intelligence and Decision Management Solutions and Econometrics.

In this Data Science with SAS Certification Course Tutorial, learners will get an introduction to SAS, SAS Operators and Functions, SAS Procedures, SAS Format, SAS Macros, Advanced Base SAS and much more. Not only these, but they will also get hands-on exercises on different SAS concepts such as Using PROC SORT for sorting the results, listing ODS, finding mean using PROC Means and print using PROC PRINT.

At the end of this Data Science with SAS training by Uplatz, learners will be able to upgrade their skills on Data Science with SAS alongside other analytical tools.

The basic structure of SAS consist of

==DATA step, which recovers & manipulates data.

==PROC step, which interprets the data.


3) What is the basic syntax style in SAS?

To run the program successfully, and you have the following basic elements:

• There should be a semi-colon at the end of every line

• A data statement that defines your data set

• Input statement

• There should be at least one space between each word or statement

• A run statement

For example: In file ‘H: \StatHW\yourfilename.dat’;


4) Explain data step in SAS

The Data step creates a SAS dataset which carries the data along with a “data dictionary.” The data dictionary holds information about the variables and their properties.


5) What is PDV?

The logical area in the memory is represented by PDV or Program Data Vector. At the time, SAS creates a database of one observation at a time. An input buffer is created at the time of compilation which holds a record from an external file. The PDV is created following the input buffer creation.


6) What are the data types does SAS contain?

The data types in SAS are Numeric and Character.


7) Which statement does not perform automatic conversions in comparisons?

In SAS, the “where” statement does not perform automatic conversions in comparisons.


8) What is a method to debug and test your SAS program?

You can debug and test your SAS program by using Obs=0 and systems options to trace the program execution in log


9) What is the difference between nodupkey and nodup options?

The difference between the NODUP and NODUPKEY is that NODUP compares all the variables in our dataset while NODUPKEY compares just the BY variables


10) Name validation tools used in SAS

For DataSet : Data set name/ debug Data set: Name/stmtchk

For SAS Macros variables: Options: mprint mlogic symbolgen


11) What does PROC print, and PROC contents do?

To display the contents of the SAS dataset PROC print is used and also to assure that the data were read into SAS correctly. While PROC CONTENTS display information about a SAS dataset.


12) What is the use of function Proc summary?

The syntax of proc summary is the same as that of proc means. It computes descriptive statistics on numeric variables in the SAS dataset.


13) What Proc glm does?

Proc glm performs simple and multiple regression, analysis of variance (ANOVAL), analysis of covariance, multivariate analysis of variance and repeated measure analysis of variance.


14) What is SAS informats?

SAS INFORMATS are used to read, or input data from external files known as Flat Files ASCII files, text files or sequential files). The informat will tell SAS on how to read data into SAS variables.


15) Name types of category in which SAS Informats are placed

SAS informats are placed in three categories,

• Character Informats : $INFORMATw

• Numeric Informats : INFORMAT w.d

• Date/Time Informats: INFORMAT w.

21) What is the difference between INPUT and INFILE?

•INFILE statement is used to identify an external file

• INPUT statement is used to describe your variables


22) State the difference between INFORMAT and FORMAT ?

• INFORMAT: To indicate SAS that a number should be read in a particular format

• FORMAT: To indicate SAS how to print the variables


23) What is factor analysis?

Factor analysis is a common term used for a family of statistical techniques associated with the reduction of a set of observable variables in terms of a small number of latent factors.  The main goal of factor analysis is data reduction and summarization.


24) How you can read the variables that you need?

You read the variables using input statement with column /line pointers, informats and length specifiers.


25) What are the special input delimiters used in SAS?

Special input delimiters used in SAS are DLM and DSD.


26) How SAS treats the DSD delimiters?

When you define DSD, SAS treats two consecutive delimiters as a missing value and removes quotation marks from character values.


27) What is the good SAS programming practices for processing large data sets?

The good SAS programming practices for processing large data sets is to sort them once using firstobs= and obs=


28) How to include or exclude specific variables in a data set?

To include or exclude specific variables in a data set you can use DROP, KEEP Statements and Data set Options.


29) How SUBSTR function works in SAS?

The SUBSTR function is used to abstract substring from a character variable.


30) What SAS features do you use to check errors and data validation?

To check errors, use the Log, and for data validation use things like Proc Freq, Proc Means or sometimes Proc print to see how data looks.


31) What are the ways to do a “table lookup” in SAS?

There are five  ways to do a “table lookup” in SAS which include:


2. Match Merging

3. Direct Access

4. Format Tables

5. Arrays


32) How will you generate test data with no input data?

You will generate test data with no input data using “put” statement and “Data Null”.

The “floor” returns the greatest integer less than/equal to the argument. Whereas the “ceil” function returns the smallest integer greater than/equal to the argument.


34) What are the difference between SAS functions and procedures?

The difference between SAS functions and procedures is that

• Procedures expect one variable value per observation

• Functions expect values to be supplied across an observation
