Hello there, I would like to model a distribution that has a lot of zeros and numbers between 0 and 1. There is a gap between 0 and 0.12 with no cases at all. See picture attached. I discovered the PROC FMM, but for some reasons the predicted values are quite off despite the Pearson Statistics was close to the sample size. Here are my codes: proc fmm data=dataset; model HU_flip=x1 x2 x3 x4 x5 x6 x7 x8 x9/dist=truncnormal (0,.) link=log; model HU_flip= /dist=constant (0); probmodel x1 x2 x3 x4 x5 x6 x7 x8 x9; output out=outfile predicted=poutcome; run; Are my codes seems ok? Please advise? Thank you so much! Yvonne
