The signed Chi-square measure for mapping

Visvalingam, Maheswari


Maheswari Visvalingam


When interest extends beyond purely univariate considerations there is no fixed rule governing the ordering of spatial samples for mapping and statistical analysis. Ratios and numerical differences have conventionally been the basis for comparing samples. As both these are known to be influenced by variations in sample size, they are unsuitable for the comparison of demographic samples which vary greatly in size. Where necessary, the effect of sample size can be accommodated by a modified form of the X2 test statistic which is described in this paper.
