Dear listers:
I am doing MLE using command in Stata, -ml-
before I type: ml maximize, following the instruction of booklet of "Maximum
Likelihood Estimation with Stata"(by William Gould and William Sribney).
I type: -ml check- first
The luck thing is that after -ml check-, the information I got is that the
program I wrote has passed the all tests.
It seems that my estimation may go well.
however, when I type: -ml maximize-
the information I get is as follows:
initial: log likelihood = -2262.0106
rescale: log likelihood = -566.9123
rescale eq: log likelihood = -319.86063
initial values not feasible
r(1400);
then, whole process of ml stops, and I can not get anything.
Does anyone have this kind of experience and how to solve this?
Thank you very much and have a nice day
Jitian
