I am running a mixture logit model on a sample of 10,000 cases. The model takes a long time (3-4 hours) to run, which makes it nearly impossible to try different specifications and such. It probably makes sense to use a subsample for exploratory analysis then fit the final model on the full sample.

This post describes how to draw a random sample in R.
