Dear all,
I am trying to run a GAM using MGCV. When I include offset:
gam1 <- gam(Presence~s(Spd)+offset(effort_m), family=binomial, data=porp)
I receive the following warning:
Warning messages:
1: In newton(lsp = lsp, X = G$X, y = G$y, Eb = G$Eb, UrS = G$UrS, L = G$L, :
Fitting terminated with step failure - check results carefully
2: glm.fit: fitted probabilities numerically 0 or 1 occurred
3: glm.fit: fitted probabilities numerically 0 or 1 occurred
How can I correct this?
Kind regards,
Lauren
