PROC FMM Two Distributions from Different Families

graybarski — Wed, 07 Feb 2018 20:03:14 GMT

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."
