SAS is a dominant force in the world of analytics. While some may argue it is on its way out, a quick query of current Data Scientist job listing in the NYC area shows many companies are still looking for SAS experience.
Luckily for us, SAS has a free University Edition that we can work with to learn SAS for free.
You can Google SAS University Edition or follow the link below:
Here is SAS Studio. The Left panel of the screen manages folders and other admin tasks. The right panel is where we type our code. We are going to start with a very simple task of creating a small data set of car names, # of cylinders, and # of doors.
Here is the code, I will explain below the picture.
Now to breakdown the code (note the ; (semicolon) at the end of each line)
DATA cars; -- this names our data set
INPUT NAME$ CYLINDERS DOORS; -- names our variables (or columns if you
will) note the $ after NAME - this
indicates NAME is
datalines; -- the data to input into our set will follow below
you may see some people use CARDS; in place of
datalines I believe this dates back to earlier
versions where one told how much memory to associate
to each row. Now they are interchangeable.
Miata 4 2
Sonata 4 4
Corvette 8 2
Mustang 8 2
Civic 4 2
Accord 4 4
Elentra 4 4
; -- end of datalines
RUN; -- run command - like the go in SQL
Now click the Run icon above your code
And view the output – we have created a data set – congrats!!
