Does anyone know where I can find the derivation of the third moment of the joint count statistic? I found this similar question answered in the past:
http://stats.stackexchange.com/questions/59913/need-derivation-of-join-count-variance-spatial-autocorrelation-stat-know-wherneed derivation of join-count variance (spatial autocorrelation stat), know where it is?
but since I am interested in the skewness of the statistic I need the third moment, when the null distribution is non-free sampling (restrict to the number of locations).
Thanks in advance!
