I want to request for a casewise diagnostic in the OLS regression.
The Casewise Diagnostic is to find the outlier in a regression.
It's can be easily find with SPSS program.
However in SPSS, we have to manualy delete the observation that found
to be outlier.
So, can gretl make an option before running a regression.
User can click an option (with any number of standard deviation) that
automatically not to include the outlier observation to the regression.
However the result have to inform the observation that become outlier.
