{"Image DocumentName": "Join Count Statistic Formulae for Calculation", "Image ImageDescription": "Test Statistic given by: Z= Observed - Expected. SD of Expected. Expected given by: Standard Deviation of Expected given by: Where: k is the total number of joins (neighbors) pB is the expected proportion Black. pW is the expected proportion White. m is calculated from k according to: Note: the formulae given here are for free (normality) sampling. Those for non-free (randomization) sampling are substantially more complex.
