A discriminant analysis method, called the WHIDD-analysis is presented. It is rather similar to Holley's G-analysis. However, it does not utilize any component analysis and is thus cheaper and simpler to use. The WHIDD-analysis uses the weighted H-index as the E-correlation coefficient. In two different sets of data only one person out of 32 were erroneously classified. This was the same accuracy as the more complicated weighted G-analysis had shown. The WHIDD-analysis seems to be an interesting, cheaper alternative.
