Dear, I'm very new to R Gui and I have to make an assignment on Gamma Regressions. Surfing on the web doesn't help me very much so i hope this forum may be a step forward.
Well since you are so honest about it being homework try Googling for lognormal gamma regression The top hit from where I am sitting is an extensive set of notes with examples in R although beware the use of _ for <-
The question sounds as follows: The data set is in the library MASS first install library(MASS) then type data(mammals) attach(mammals)
At this point you should complain that you are being taught poor practice as it is nearly always better to use the data= parameter and not attach data frames.
Assignment: Fit the gamma model and lognormal model for the mammals data. I appreciate any help you can provide. Best Wishes, Louisa -- View this message in context: http://r.789695.n4.nabble.com/Gamma-Lognormal-Model-tp3165408p3165408.html Sent from the R help mailing list archive at Nabble.com.
