WebVR = l - (proportion of cases in the mode) The value of VR reflects the following logic: The larger the proportion of cases in the mode of a nominal variable, the less the variation among the cases of that variable. By subtracting the proportion of cases from 1, VR reports the dispersion among cases. This measure has an absolute lower value of ...
