The technical note summarizes the calculations required in the following steps 1 Postulate an initial set of variables describing head dynamic response. 2 Eliminate variables of marginal potential using the ratio of between-cell variance to within-cell variance as a criterion. 3 Perform a principal components analysis on the retained subset of variables in order to identify a set of transformed variables accounting for large between-cell variation. 4 Conduct an analysis of variance on each transformed variable. 5 Examine residuals to yield additional information.
