GAM download in stata

[Monil Majmundar]

how to download GAM (generalized additive model) in stata ?

[Leonardo Guizzetti]

You can start with -search generalized additive models- and see what user-created packages exist.

I have downloaded but it shows following error

GAMFIT failure, $.out not found
file $.out not found

[Bjarte Aagnes]

The complete error message was maybe:

GAMFIT failure, gam.exe not found
GAMFIT failure, $.out not found

and running

which gam
findfile gam.exe

might show you have installed gam.ado in the PLUS directory, but Stata cannot find gam.exe

if so, you may try:

copy "http://fmwww.bc.edu/repec/bocode/g/gam.zip" "`c(sysdir_plus)'g/" , replace
unzipfile "`c(sysdir_plus)'g/gam.zip" , replace

then test

which gam
findfile gam.exe

sysuse auto , clear
gam mpg weight displacement, df(weight:3, displ:4)
gam foreign mpg, family(binomial) df(3)
xi: gam foreign mpg i.rep78, family(binomial) df(mpg:2)

Dear Bjarte (and All),

I found this post (about GAM) and your advice useful. I will very much appreciate your further advice about the following:

If I run GAM using a dataset like auto.dta, GAM works. However, using my own dataset, STATA returns the following message:

GAMFIT failure, $.out not found
stats not found

What am I doing wrong? And how do I fix it?

Thanks in advance.

Regards,
Itai
