Hi there,
i tried to run an ordered logistic regression with polr. so far it
worked after i turned my data into factors.
but hereĀ“s my problem:
my output is like this:
Call:
polr(formula = factor(fulltest[, 1]) ~ factor(fulltest[, 2]) +
factor(fulltest[, 10]), method = "logistic")

On the definitional question, some texts do indeed consider multi-category
logistic regression as a glm. But the original definition by Nelder does
not. I've never seen polr considered to be a glm (but it way well have
been done).
Adding random effects is a whole different ball game: you need

I think the options are pretty limited for mixed-effects ordinal regression; it
might be worth taking a look at Laura Thompson's R/Splus companion to Alan
Agresti's text on categorical data analysis:

I'd like to estimate an ordinal logistic regression with a random
effect for a grouping variable. I do not find a pre-packaged
algorithm for this. I've found methods glmmML (package: glmmML) and
lmer (package: lme4) both work fine with dichotomous dependent
variables. I'd like a model similar to
Hi,
How can I do ordered logistic regression in svyglm?
Thanks,

You might also try
library(Design) # also requires Hmisc package
mod1 <- lrm()
mod1
summary(mod1)
anova(mod1)
