Using SAS functions

“

- [Instructor] In this section, I want to show you to use some built-in SAS functions to assist in creating new variables, functions like sum, absolute, exponentiate, round, and so forth, and we'll use all these in a data step to create our new variables. And by the end of this section, I want to show you how to create your own user-defined function to be used inside of a data step. So here I have a function called mydivision in R with two arguments, numerator and denominator. I want to be able to return a value of zero if the denominator is zero. Otherwise, I just want to return the value numerator divided by denominator. So to create a new variable using built-in SAS function, we'll do it the exact same way in R. Here we'll use it in our data step. We have our data statement, our set statement, and here I'm creating a variable called log_price which I'm just setting equal to the log of msrp, meaning I'm just taking the log of every element in that variable. Now, most of these…
