Hi All;
The following question is directed more to statisticians on the list.
Suppose I have a normal random variable. Is there a transformation that I
can apply so that the new variable is slightly positively skewed.
I greatly appreciate your help.

I think the box.cox function in package car can do this.
x - rnorm(1000)
hist(x)
library(car)
hist(box.cox(x, p=0.5))
Play around with different powers.
Best,
Matthias
