st: Re: Variable selection

["Sherriff, Martyn" <martyn.sherriff@kcl.ac.uk>]

I have a dataset with 125 variables and I only need to analyse a subset of them. Rather than write a 'locaI' to include the variables that I wish to analyse I have tried to exclude the variables that I do not want as follows:

qui:findname
foreach v of varlist `r(varlist)'{
	if "`v'" !="chew" {
	kwallis `v',by(ur6)
	}
	}
And this works for the exclusion of a single variable. However if I include more than one variable:

	if "`v'" !="chew" |" `v'" !="subject" {

then no variables are excluded.

Could somebody advise me of the syntax error that I am making - or an improved way of solving the problem?

Thanks,
Martyn
