When using the kurtosis function from the pyspark module pyspark.sql.functions.kurtosis(col), is the result in excess of the Normal distribution? ie. is 3 already subtracted from the kurtosis to yield k-3? Or would we have to calculate the excess ourselves?

I could be wrong, but since pyspark gives negative values for its kurtosis, I assume that it is excess kurtosis which it has already subtracted 3 from its calculation.
