R help - Sep 2020 - How to model multiple categorical variable in r, using gee model

Good morning.
I'm a student at present working on my final year project.
Kindly asking for help on how to model longitudinal categorical data.

In my data set I have the following variables :type of crime,year,   month,
date and time.treating type of crime as the response variable and there's
12 levels  (Type of crime), while the rest of the variables are
independent.
What model will best fit my data?

I have tried using geeglm And this does show differences in correlation
matrix that should be selected as the best model, secondly I tried using
multgee package "multLORgee" which never have me outputs and lastly I
tried
using multnom the function returns the same AIC in the working correction
matrix,
How do i solve this problem
Thank you.

Hi Augustinius,
You have been set a problem that requires a lot more information than
is in your request. Also, you have flagged it as a "homework" problem,
so you are unlikely to get much help on this list. Sadly, this sort of
problem sometimes arises when being nice to the instructor is more
important than having the relevant knowledge and I can't help you with
that.

Hi Augustinius,
You are probably familiar with some of these:

http://finzi.psych.upenn.edu/R/library/geepack/html/geeglm.html
https://faculty.washington.edu/heagerty/Courses/b571/homework/geepack-paper.pdf

Good luck with it.

Jim

which working correction matrix will better fit the model (model selection ) for
the fact that all the model with different correlation structure keeps returning
the same outputs (I do not observe an difference) hence my concern as it
supposed not be the case.

Thanks for coming through sir. I will check it out.
