GAM: Remedial measures
I fitted a GAM model with Poisson distribution to a data with about 200
observations. I noticed that the plot of the residuals versus fitted values
show a trend. Residuals tend to be lower for higher fitted values. Because,
I'm dealing with count data, I'm thinking that this might be due to
overdispersion. Is there a way to account for overdispersion in any of the
packages MGCV or GAM?

GAM: Getting standard errors from the parametric terms in a GAM model
I am new to R. I'm using the function GAM and wanted to get standard errors
and p-values for the parametric terms (I fitted a semi-parametric models).
Using the function anova() on the object from GAM, I only get p-values for
the nonparametric terms.
Does anyone know if and how to get standard errors for the parametric terms?
Thanks.

GAM: Overfitting
I am analyzing particulate matter data (PM10) on a small data set (147
observations). I fitted a semi-parametric model and am worried about
overfitting. How can one check for model fit in GAM?
