SAS says data contains no columns when using linear regression

cedge113 — Wed, 07 Mar 2018 05:54:11 GMT

I'm new to SAS (using the university edition) and am having issues with using Linear Regression.

I loaded a CSV file and then in Tasks and Utilities > Tasks > Statistics > Linear Regression I selected WORK.BP (BP = filename) for my data. When I try to select my dependent variable SAS says "No columns are available."

The CVS file appears to have loaded correctly and has 2 columns so I can't figure out what the issue is.

Thanks for the help.

This is the code I used for loading the file:

data BP;
infile '/folders/myfolders/BP.csv' dlm =',' firstobs=2;
input BP  $Pressure$;
run;

And this is what the output looks like

Remove the dollar signs from the INPUT statement. They are making both of your variables character. Since regression requires numeric variables, there are no variables that can be used for regression. (Yes, there are cases where a character variable is used to create dummy variables, but that is not the case here.)

Remove the dollars from your input statement, so that the variables are created as numeric.
