xrigls command

[Crystal Gonzales]

I've been trying to use the xrigls command however the regression for SD curve was not shown and there is a line "res invalid name". It indicates that it is r198 error.
I hope someone can help me.

You'll increase your chances of a useful answer by following the FAQ on asking questions - provide Stata code in code delimiters, readable Stata output, and sample data using dataex.

This appears to be an internal problem with the procedure. With a user written procedure, you can either try to open the ado file and diagnose it yourself, or contact the procedure's authors. It is possible that something you have entered in the command line is causing the problem, but it's hard to guess what – do you get this problem when you run the example provided with the procedure?
