Question about _NAME_ or _TYPE_ variable error

[Tim_sas_]

Hello,

I have a question regarding an error message I receive. I run a regression on a constant (please see code below). It works without any problems, but it shows the following warning:

The variable _NAME_ or _TYPE_ exists in a data set that is not TYPE=CORR, COV, SSCP, etc. 

Proc reg data=data_in;
Model Variable_1 = ;
ODS Output parameterestimates = data_out;
run;

I do not really understand the meaning of this error in this particular context and would be very glad if someone has an idea.

Many thanks,

Tim

That is just a WARNING, not an error.  PROC REG can use covariance table as input (TYPE=COV) so it is just asking if you perhaps meant to have given it a covariance table instead of a regular table.  You could just drop or rename the _TYPE_ and/or _NAME_ variable especially since your code does not appear to be using them.
