Hello!
I'm new to SAS (it's my first time using it; I'm an R user).
I'm interested in conducting a Poisson regression on the following data:
Game Success Attempts
1 4 5
2 5 11
3 5 14
4 5 12
5 2 7
6 7 10
7 6 14
8 9 15
9 4 12
10 1 4
11 13 27
12 5 17
13 6 12
14 9 9
15 7 12
16 3 10
17 8 12
18 1 6
19 18 39
20 3 13
21 10 17
22 1 6
23 3 12
For each game, Y(i) represents the number of free throws made out of n(i) attempts, which are binomial (n(i), pi(i)).
I want to fit the model pi(i) = alpha.
I was able to do this in R showing the value of alpha equal to .42.
I think I can do this using the Proc genmod on the data, as well as a goodness of fit chi-squared test. Additionally I would like to run the maximum likelihood (ML) and quasi-maximum likelihood method (QML) analysis on the dataset.
Hi Andrew, this is logged into the Communities Admin account. I happened to be online and saw your post and that you are a new SAS user. Welcome! It is a bit slower on Sunday here in the community but I'm sure you'll get an answer on Monday if not before. I apologize earlier when your message was caught in our spam filter - that should not happen again.
In the meantime, I did this search in the community - in case there is an answer out there: https://communities.sas.com/search.jspa?view=content&resultTypes=&dateRange=last90days&q=poisson&ran...

Hi, You should post it at
in: SAS Statistical Procedures
and proc genmod can do Poisson Regression .
