Use the drop-down menu to select the method used for computing differences between the observations . The DGOWER method is selected by default.
Calculates the correlation transformed to the Euclidean Distance between pairs. Select this method only when variables are either ratios, or positive and continuous. Calculates the squared root of the chi-squared coefficient between pairs. Calculates the chi -squared coefficient between pairs. Calculates the squared root of the phi -squared coefficient between pairs. Calculates the phi -squared coefficient between pairs. Refer to the SAS PROC DISTANCE documentation for more information.
