Hi,Dear Professor Wood,
I am studying the generalized additive model(GAM)
and I have read your related papers,especially the book named "Generalized
Additive Models:An Introduction with R".I am benefit a lots.However,I also
have some questions about GAM models.

First,Is there some restrictions on the sample size? For example,I am
studying
the GDP and foreign direct investment on 29 provinces in China(N=29).Whether
or
not N is too samll? If so,could I use pooled data(N=29,T=5)?

Second,Could I use the "mgcv" packages to implement panel data model
through
adding
specific fixed effect and time fixed effect as the generzlied mixed
model?(eg. adding factor(s)).


Thanks very much in advance.


Best Regards,
Wanhai
