Thanks, Ulrich Frick. The recommended paper is very useful for me.

I read that the skewness and kurtosis (two statistical functions) are

used in capital markets to assess the state of player agitation

in the market. The primary data are frequency and operation volume

of sales of shares.

I'd be interested to know details about how to interpret the

skewness and kurtosis to characterize mental status of a

human agent. Also I would like to know if anyone used them

for evaluation of a human (car) driver.
