My problem is the following. I have data on income in both values and
income intervals. Using a log likelihood for both sub
samples, I want to get parameters of the joint sample. My problem is how to
define the income intervals in Gretl, and apply them to a
cumulative density function, normally distributed ( not standard cdf).
I want to express the income intervals as a difference between
cumulative density functions at each point. Any idea how to do that??
Hope I’m clear. It is clear that I’m a beginner in Gratl.
If I understand correctly what your problem is, your model may be
estimated via the intreg command. If you want to use other distributions
than the normal, then you need to write a script and use the mle command.
