Dear List
1. I am considering using ZIP with Sample Selection (in Full
Information Maximum Likelihood). Has anyone written a code for this,
kindly guide me to the right direction.
2. Is it appropriate to apply a count model to a data where the only
count present in the data are: 0, 1, 2.  Counts above 2 are possible
but very extremely rare. Another consideration, the occurance of
counts are not equally probable. 0 is more probable than 1. 1 is more
probable than 2, Hence 3 and above are much less probably to even
unlikely. Thanks in advance.
James
