Hi there,
I have two questions about "mim".
1. I used "estat store" after "mim: reg" model in Stata. It gave me an error
msg of "last estimation results not found, nothing to store". Does that mean
I can't use "estat" after "mim"? Thanks.
I wonder if you need the -storebv- option? See -help mim##replay-,
and the warnings it gives about post-estimation commands after -mim-.
2. I used the following command
mim, category(fit): ivregress 2sls cbcl_tot ${indv} (safe = total_crime),
first
But Stata didn't show me the first-stage result.
Could anybody tell me why? Thanks.
Here is my guess (possibly wrong): A command can compute all sorts of
intermediate results. -mim- isn't going to give you all those
intermediate numbers. It is just going to give you the final
estimates. My guess is that it doesn't even estimate a single set of
coefficients for the first stage results, i.e. it may compute, say,
20 different first-stage estimates, but it doesn't bother to combine
them into a single set of first-stage estimates.
If you wanted, you could add the -noisily- option to -mim-. But my
guess is that it would just deluge you with output.
