Nonparametric seems to me to be an unfortunate term for describing
fixed effects: e.g. the effects of your explanatory variables are still
parametric (often linear). Than again, statistics is full of
unfortunate terms. However this use of nonparametric is not common
(long may it stay that way), which might explain why you had trouble
finding any Stata implementations.
Anyhow, fixed effects models can be estimated using the -xt- commands
with the -fe- option. See: -help xt-
Hope this helps,
