Statistic of chi-square independence


The measure of the independence of the characteristics listed in the table of independence. Such statistics always take values greater than (or equal) zero and the maximum value depends on the size of the array. The value of statistic is the basis for the construction of many measures of independence (consequently also correlation) between variables, in particular for qualitative features, such as the C-Pearson Factor.
