Dear R users, I have had a problem using the "step" function for the selection of the variables from a gamma model with log link function.
CODE: step.glm.gam1.infroma <- step(glm.gam1.infroma, direction = "backward", k=2) ERROR MESSAGE: Error in glm.fit(x[, jj, drop = FALSE], y, wt, offset = object$offset, : inner loop 1; cannot correct step size In addition: Warning message: step size truncated due to divergence Could someone help me???
