st: Streg, Distri(logn) convergence issues

["Shon Hiatt" <shon.hiatt@gmail.com>]

I am using a natural logarithm event history analysis [streg,
distribution (Logn)] and I continually obtain the following errors
after multiple iterations:

Discontinous region encountered
Cannot compute an improvement

Should I change the convergence tolerances (as shown under the Stata
help "Maximize")? Any suggestions would be appreciated.

Thank you,
Shon
