We brought complete training videos for free on BASE SAS, ADVANCED SAS, TLFs and Clinical SAS.
If time permits i will do work related project videos such as complete generation of DSMB reports, Randomization reports, Screening and Enrollment reports etc....
Keep Learning for free!
Thanks,
Chandana :-)
**************Note: there is a purpose, that i didn't share the study material, while watching video write down your own notes/code from what you understood, which gives you better understanding than reading from the books **********************************
Introduction :
SAS Full form- Statistical analysis system.
It is developed at North Carolina State university, Originally developed for Agricultural Research Purposes, developed in between 1960’s and 1970’s
SAS = Data warehousing Tool + Statistical Package
The main functions of Data Warehousing Tool are ETL – Extraction, transforming and Loading and Reporting
The main function of Statistical Package is Data Analysis So, SAS can do all Data management, Data cleaning, Data manipulation, Data Analysis and Reporting work. SAS features, It can process unlimited rows and columns, Built in statistical functions for performing analysis, Several numeric and characters functions for data manipulations, Interact with multiple database and operating systems.
SAS Based Industries, Health care and pharmacy, Financial services, Retail and Telecom, Marketics, Analytics etc.,
SAS enables you to, Enter, retrieve and manage your data easily Create slick reports and pretty pictures Analyze your data statistically and mathematically .
SAS programming:
SAS Windows:
Editor Window – We can write, Edit and submit our SAS programs
Log Window – Contains all the notes like Commands/program lines/statements submitted, execution details and displays errors and warnings if any Contains all the notes in 4 different colors – Black, Blue, Green, Red Black - Commands/program lines/statements Blue - Execution details Green - warnings Red - Errors
Output Window – Results are printed in Output window
Explorer Window – Storage place for all SAS Files. Contains folders like libraries, favorite folders, computer, file shortcuts etc.,
Results Window – Used to navigate the output window, serves much like a table of contents for Output Window.
SAS Program steps: Data step and Proc step
Data Step :
(1) Starts with keyword ‘Data’ , Used to create and modify data,Create a SAS data set
(2) Proc step Starts with key word ‘Proc’ , Generate results or reports
workflow in SAS
Data Step --- Create Data/Modifying Data –---Proc Step -----Data Analysis/ Reporting
SAS Files:
There are two types of SAS files
(1) Dataset – SAS data is stored
(2) Catalog – Stores all macro variables, informats and formats information
SAS Dataset : Data is stored in tables which are called as SAS datasets Tables Datasets
Rows Observations
Columns Variables
SAS Libraries:
SAS Data files/sets are stored in SAS library Types of SAS libraries:
There are two types of SAS libraries,
(1) Permanent library:
SASUser and SASHelp are inbuilt permanent libraries of SAS. We can create a new SAS library by using SAS utilities or by writing the codes in the editor window. These libraries are named as permanent because if we create a program in SAS and save it in these permanent libraries then these will be available as long as we want them.
(2) Temporary library:
Work is the inbuilt temporary library of SAS. All the programs that we create are stored in this work library if we do not assign any other library to them. You can check this work library in the Explore Window. If you create a SAS program and have not assign any permanent library to it then if you end the session after that again you start the software then this program will not be in the work library. Because it will only be there in Work library as long as the session goes ones.
