Creating a Mathematical model

Barkamih — Thu, 08 Oct 2020 15:02:50 GMT

Hi all,

I'm looking for someone to write this model mathematically if you don't mind.

regards

proc GLIMMIX data=herd;
class testyear time ;
model mpd = testyear / oddsratio solution;
random herd(Time);
lsmeans  testyear / e cl oddsratio plots  ;
ods output lsmeans = MEANS;
run;

What do you mean by " write this model mathematically"?

Are you looking for some sort of raw code to duplicate the functionality?

Or an explanation of the calculations done? Read the friendly manual, i.e. the documentation for the procedure in the DETAILS section.

Something else.

You can use a CODE statement to have the code piped to a file and you can use that to help you determine your final equation if you're unsure of the format.

https://documentation.sas.com/?cdcId=statcdc&cdcVersion=14.2&docsetId=statug&docsetTarget=statug_glimmix_syntax04.htm&locale=en

code file='/folders/myfolders/glimmix_score_code.sas';

Changing the path to something relevant for you, the idea is above and then check the program created for the logic.

something like this:

y = A + b + e

Y is a binary

a fixed effect

b is random nested within 12 months

e is residual
