exact/cmh/mh) in proc freq procedure for Inferential statistics

MH mehtod in proc freq....

chisq-  is for the independent test of row and column (each cell at least 5 frequency  ).

fisher exact - is for the small sample data ( one of cell has less than 5 frequency ).

CMH- is for multiple contingency table analysis .

Why not check SAS documentation firstly ?
