st: Re: How to find out whether a variable is a dummy variable ?

[Thomas Corneli�en <cornelissen@mbox.iqw.uni-hannover.de>]

I suppose I found a way myself combining

-sum- to check whether the minimum is 0 and the maximum is 1

and

-distinct- (if installed) to check whether there are only two distinct 
values.
