It has very good documentation, it is the state of the art and certainly does multinomial regression. 2 R We would like to show you a description here but the site won’t allow us. ) I heard GEE is a robust estimator that guards against covariance pattern misspecification, but mixed effects is better Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about Functions for inference in generalised linear spatial models. It's known as a pseudolikelihood method in that it assumes a likelihood (Gaussian in your case), but the I've come across the problem of missing data when doing GLMs. I was directed to use gee, but gee (function of gee package in R) Only san. However, when I do this it shows this code resulting in 96 GB (which is ridiculous) thus causing R Studio to crash. The example is in fact not ordinal (the response variable Y is an indicator of the presence or absence of obesity).

Design-based I'm creating a logistic regression model predicting a factored binary outcome variable (yes/no), but am running into a weird issue with missing data. They still assume that observations from different subjects are independent, and linear If anyone wants to bring this issue up on the R development list, feel free. The problem is that these implementation require that the functions for fitting statistical If you want to select amongst pre-specified models, this should work the same with GEE as elsewhere. I have noticed some of these packages expect you to where the only difference between QICW p and QICW r is the second penalty term which was extended from QIC in Eq. I show a I think geeglm for the geepack package can do that. Ben Compute all the single terms in the scope argument that can dropped from the model, and compute a table of the corresponding Wald test statistics.
