Dear R users I have a problem with the selection of the variables from a gamma
model with log link function:
step.glm.gam1.infroma<- step(glm.gam1.infroma, direction = "backward", k=2)
Errore in glm.fit(x[, jj, drop = FALSE], y, wt, offset = object$offset, :
ciclo intero 1; impossibile correggere la ampiezza del passo
Inoltre: Warning message:
ampiezza del passo ridotta a causa della divergenza
Could someone help me???
Thanks
Silvia
