st: clad error: sample size smaller than number of degrees of freedom

["Vivian Hoffmann" <veh4@cornell.edu>]

Dear Statalisters -

I'm trying to estimate a model using the <clad> command, but I get the
following error:

Program did not converge,
trimmed sample size is smaller than number of degrees of freedom.

even though I have 188 observations (98 non-censored) and only one
independent variable...

Any ideas on why this might be happening or how to solve it?

Thanks very much!
