Hi,

I have creaed a composite variable using scores from four different
measures. Thus, I z-scored the variables before creating the sum.  My
variable is highly skewed and is leptokurtotic. I wanted to transform
the composite variable but cannot because the the values are not
non-zero and run below zero. Is there a way I can get around this?

Thanks
Joche
