PROC FMM Two Distributions from Different Families

Hi,

 

I am wondering if it is possible to fit a mixed distribution from two or more parametric families (ie gamma and normal)) within PROC FMM.

 

for instance the following code will not run.:

proc fmm data=catch;

class gender; model count = gender*age / dist=Normal Gamma ;

run;

 

If anyone could explain if this is possible and perhaps in the case of it not being possible, why this is?

 

Thanks!

Read the manual. It says :

 

"You can specify more than one MODEL statement. Each MODEL statement identifies one or more components of a mixture. For example, if components differ in their distributions, link functions, or regressor variables, then you can use separate MODEL statements to define the components."
