Hello everyone,

I want a chi-square statistics value hence I want to user the function crosstab using n number of variables. Although this is permitted if I manually add the individual variables myself. (in the form of x = crosstab(a1, a2,...an)).

But in this scenario, I am asking the user to select 'n' number of data values (each is a column of categorical data) using a for loop. How do I input all the selected columns at once and apply the crosstab function ?

(

Maybe somthing like, a = [a1, ..., an]; x = crosstab(a); % This doesn't work though.

)
