I am currently using a GLM with Gaussian family to model fish depth~length + distance from shore:
model1 <- glm(Depth ~ length + distance from shore, family=gaussian(link="log")) There are no zero depths. I would like to use the above model with the predict function in R to generate three lines (with confidence intervals) for the depth at size for three distances, say 100 m, 500 m and 1000m. Problem is I am unable to figure out how to do this? Any advice / assistance would be gratefully received...
