How about -xtgee-? 

Something like: 
xtgee var1 var2, link(log) family(poisson) i(id) corr(ar1) t(time)

Are there any ado files or other programs that will allow Poisson estimators
for space time series in Stata? I have some rain and temperature data that I
wish to compare to malaria incidence over time, and with regular Poisson or
negative binomial regression, I face the problem of autocorrelation between
months of malaria incidence. I have done time series analysis with the ARIMA
command, but I am not sure if it is entirely appropriate for the relatively
small dataset I have (rain, temp, malaria cases over 36 months).

I have found a program within R that will do Poisson estimators for time
series (PESTS), but I'm not familiar enough with R to know how to input my
data. Does anyone know of any Stata programs that will incorporate moving
averages and autoregression into Poisson estimations?

Thanks,
Chandy John
