(in this column I have 4 values from 0 to 3 (0,1,2,3) but I want to first analyze them in only two groups: 0 vs 1+2+3)<BR />How can I unite 1 with 2 and 3 in only one group without editing my excel?<BR />thank you so much</P> Thu, 08 Jun 2023 16:35:42 GMT Davidemu 2023-06-08T16:35:42Z https://community.jmp.com/t5/Discussions/Chi-square-easy-question/m-p/601570#M80498 <P>Hello everyone,&nbsp;<BR />I'm new to jmp and I was wondering a simple thing.&nbsp;<BR />When I do the chi square test I want to compare a binary/dihcotomic variable in my Y (0 or 1) to another dihcotomic variable in the X that is 0 this time vs 1+2+3 together.

Copy and paste this expression in the formula editor for the new column.</P> <P>&nbsp;</P> <PRE><CODE class=" language-jsl">If( :X == 0, 0, 1 )</CODE></PRE> Wed, 15 Feb 2023 19:44:13 GMT https://community.jmp.com/t5/Discussions/Chi-square-easy-question/m-p/601605#M80499 Mark_Bailey 2023-02-15T19:44:13Z
