Hi,
I hope someone can offer useful advice on this. I have a
two-stage model (a variation on Heckman selection). However, proper
estimation in the second stage is
posing a problem since the sample size is drastically reduced (ie. far
fewer than 30). Can
someone offer a solution? Am I just out of luck. Any and all
opinion/advice is welcome. Thanks.
