[R] Inverse Gaussian distribution not working in glm funciton

Hello everybody, I have encountered a problem with the inverse Gaussian distribution. It is very likely that it will not work regardless of the data input. I have programmed this regression and it works fine no matter which distribution the response comes from. If you run this example (first tri

Dear David, It works! Thank you so much for your help! Louisa -- View this message in context: http://r.789695.n4.nabble.com/Inverse-Gaussian-Distribution-tp3172533p3174015.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-p

Re: [R] Inverse Gaussian Distribution

Thank you again David! I did not try it yet, cause neither the dataset nor R is on this computer. I'll try it in a few hours, as soon as possible, when I'm on my personal computer. I'll let you know if it works. I'm really curious! Thank you for your time! Best Wishes, Louisa -- View this

Thank you! But i'm wondering: if you run area <- factor(area, levels=c("C", "A","B","D","E","F") ) then you are transforming only 'area', aren't you? isn't it possible to transform the whole data like i did for agecat but now for area and area C as baseline, or are you doing so when y

Hi: "How can i manipulate the data to set the baseline of area to C? R is producing errors when I'm trying to do so." See ?relevel Dennis On Mon, Jan 3, 2011 at 12:03 PM, Louisa wrote: > > Dear, > > I want to fit an inverse gaussion distribution to a data set. > > The predictor variables are

Dear, I want to fit an inverse gaussion distribution to a data set. The predictor variables are gender, area and agecategory. For each of these variables I've defined a baseline e.g. #agecat: baseline is 3 data<-transform(data, agecat=C(factor(agecat,ordered=TRUE), contr.treatment(n=6,base
