Could you explain how this nthreads option excactly works and what value I should put there? I tried different combinations but it didn't help or maybe any other solutions ? Error occures immidiately after running the code: proc hpsplit data=table_2 seed= 123 assignmissing=branch cvmodelfit maxdepth=8 maxbranch=2 LEAFSIZE=10; class target_var ; model target_var = var1 var2 var3 ; grow chaid; performance nthreads = 5; prune costcomplexity (leaves = 6); output out=tree1; run;     Thanks ...

The target variable is a continous one so for example  one data set has 848 observations where target variable has 748 distinct values - there error occured. On the other data set is 483 observations and 453 distinct values of target variable and it works properly. It is possible to avoid this error somehow?   Thanks ... View more
