Dear All
I get following error in some of my datasets while using VGAM package.
Error in backsolve(Rmat, rinv) :
singular matrix in 'backsolve'. First zero in diagonal [1057]
Kindly advise how to tackle this error.
My formula reads like this: vgam(cbind(list of species)~s()+s(),
binomialff(multiple.responses = TRUE,, bred = TRUE), Trace = TRUE, maxit =
TRUE)
Your kind response is highly appreciated.
Best Regards
