I want to get the maximum likelihood estimates for 4 distributions: exponential, Gamma, Log-normal and weibull. I cant figure out the code since I dont have the parameters. the data set is attached below, claims being the dependent variable.
My questions are:
How do i find model paramters for the mentioned distributions?
How do i compute log likelihood for the mentioned distributions?
Im using SAS Studio online.
Hello,
You need to use PROC SEVERITY (SAS/ETS).
The 4 distributions you mention are among the predefined SEVERITY distributions of this procedure.
If you don't have SAS/ETS, even PROC UNIVARIATE (base SAS) can be used for the quite common distributions that you would like to fit.
See the documentation for correct usage of PROC SEVERITY and PROC UNIVARIATE.
Kind Regards.
Hello,
Thank you for your reply.
Okay i will do this
Have a good day
