Kurtosis and Skewness

Hello,

 

I am trying to figure out the correct formula for kurtosis. I have already been using the formula for skewness as:

GLOBAL MEAN ( ((inputlayer) - mean) / SD) ** 3)

 

what would the kurtosis formula be?

 

Thanks in advance

Re: Kurtosis and Skewness

Hi bfred,

 

You can check out the bimodality model I provided in this thread:

It calculates skewness and kurtosis. This was my Reference for the formulae:
