Jim Lindsey's repeated package has the function gnlmm which will fit beta regressions with a random intercept and one level of nesting. I don't know of any other options. Cheers, Simon. Not sure On Mon, 2008-07-14 at 19:16 -0700, Daniel Malter wrote: > I have a connector-question to that. Is be

I have a connector-question to that. Is beta-regression available for repeated measures or panel data and if so is it available in R? thx, Daniel Kevin J Emerson wrote: > > R-devotees, > > I have a question about modeling in the case where the response variable > is > binary. > > I have a c

Re: [R] modeling binary response variables

2008-07-14 Thread Simon Blomberg
Wait, are the proportions (probabilities) based on discrete data, or are they truly continuous? If the latter, then beta regression might be more appropriate (e.g. package betareg). If the former, include the sample size for each proportion in the call to glm using the weights= argument. Or set the

2008-07-14 Thread Daniel Malter
Hi Kevin, you mean an s-shaped relationship of a variable with your response? So you have a response that is strictly constrained to the interval 0,1 or, and these limits are not due to truncation or censoring (i.e. your response variable is truly a proportion). This sounds like a good applicatio

[R] modeling binary response variables

2008-07-14 Thread Kevin J Emerson
R-devotees, I have a question about modeling in the case where the response variable is binary. I have a case where I have a response variable that is the probability of success, and four descriptor variables, The response has a sigmoid response with one of the variables. I would like to test for
