# Skewness and kurtosis values in descriptives

Hi all,

I already posted this on Twitter but was referred to the forum, so I'll bring it up here again I recently started using JASP but tend to doublecheck relevant values in R. Today I calculated simple descriptives for my data. In R, I am using the library pastecs, and the values for skewness and kurtosis (as well as the SEs, obviously) differ from those provided in JASP. The general direction is the same (i.e., I have one non-normally distributed variable with high skew and kurtosis), but the numeric values differ quite a bit. All other values are identical though. Any ideas why that might be? Because I am unsure which ones to report now.

Thanks in advance!

This is how we calculate skewness and kurtosis:

I'm not sure how the R package calculates these statistics. Could you attach the csv you are using to calculate these statistics so I can check it?
