R function for computing Simultaneous confidence intervals for multinomial proportions
Dear all,
Does someone know an R function implementing the method of Sison and
Glaz (1995) (see full ref below) for computing Simultaneous confidence
intervals for multinomial proportions?
As alternative method, I think to boostrap the mean of each proportion
and get in that way confidence interval of the mean.
I observed 21 times a response that could be one out of 8 categories

"metafor" package, proportions: single groups wrt to a categorical dependent variable
Dear Dushanthi,
Please keep your e-mails on the R-Help list, where Michael has already given you some excellent advice. As Michael already explained, metafor can handle proportions, but does not have any specific functionality for categorical variables with more than 2 levels (at the moment). So, if it is logical and possible to do so, you could collapse the levels of the categorical outcome to 2

question regarding hypothesis testing in contingency tables
Hi R-users!
I have the following example:
a<-data.frame(cat=c(5,10,15), dog=c(5,10, 15), mouse=c(10,10,20))
b<-data.frame(cat=c(15,10,5), dog=c(15, 10, 5), mouse=c(20,10,10))
rownames(b)<-c("scared", "happy", "sad")
rownames(a)<-c("scared", "happy", "sad")
Let's say that a and b are 2 contingency tables and 5,10, 15, 20

p value for coefficients in multinomial model
Dear all,
1)how can I easily get p value for the coefficients of factors in a multinomial model?
2)why the p values for "type III" test with Anova are not identical to that from SAS?
for example:
A,B and C are categorical variables,but the proportions of each level in each categorical variables are not balance. Y is a nominal variables(>=3 categories);

[PATCH] [QEMU-DM] Modem control line & msl/mcr register support
This patch enables handling of the modem/flow control lines of a serial port
when the backend for the virtual port is a physical serial port. During
initialization, it tries to load the msr with the detected status from the
real port (this is consistent with physical uart, which starts with its msr
values set according to the status of the modem status lines). If the ioctl
returns -ENOTSUP, then

Mixed effects multinomial regression and meta-analysis
R Experts:
I am conducting a meta-analysis where the effect measures to be pooled
are simple proportions. For example, consider this data from
Fleiss/Levin/Paik's Statistical methods for rates and proportions (2003,
p189) on smokers:
Study N Event P(Event)
1 86 83 0.965
2 93 90 0.968

ungrouped data for multinomial regression
Thanks for helping me out with the thing of quotation marks. I finally
could save time running programs at the university and home.
One additional question for all of you. I'm starting to be familiar
with multinomial regression models. Actually I'm doing some exercise
with the pneumo data that appears in Faraway library. The database has
24 observations and I want to study the probability

multinomial confidence interval
Hi R users!
Is there a function that extracts the simultaneous confidence intervals for multinomial proportions as described by Sison and Glaz 1995? or anyone else for that matter?
I have seen that SAS has macro for this ( http://www.jstatsoft.org/v05/i06) and i was wondering if R had something similar?
Thank you and have a great day ahead!

Function for Estimating Fractional Multinomial Logit Model?
I need to estimate a model that predicts the proportional split of
travel among the vehicles of a household based on vehicle
characteristics such as age, fuel economy, and travel cost per mile. The
model estimation dataset has a record for each household vehicle with
information about the vehicle, the household, and the proportion of the
total household vehicle travel using that vehicle. I have

Multinomial Nested Logit package in R?

simultaneous confidence intervals for multinomial proportions: sample size
Hello!
I want to calculate simultaneous confidence intervals for a nominal variable with three categories: "yes", "no", "partially" and I expect that far more than 5 samples fall into each category.
I have read that Glaz & Sison's method is only appropriate for variables with 7 or more categories. Therefore, the Goodman method seems like a good idea.
I have
