F-Tests in generalized linear mixed models (GLMM)
Hi!
I would like to perform an F-Test over more than one variable within a
generalized mixed model with Gamma-distribution
and log-link function. For this purpose, I use the package mgcv.
Similar tests may be done using the function "anova", as for example in
the case of a normal
distributed response. However, if I do so, the error message
"error in eval(expr, envir, enclos) :

gam(mgcv) starting values
Hi all!
I?ve got some problems with the function gam (library mgcv). For some
models I get the error message :
Error: no valid set of coefficients has been found:please supply
starting values
In addition: Warning message:
NaNs produced in: log(x)
This is a shortened code I used:
gam(y ~ M1 + M3 + M4 + M5 + M6 + sex + M1*M3 + s(age),
family=Gamma(link ="identity"),
weights=days)
