INFORMATION POINT: wilks ' lambdaWilks' lambda is a test statistic used in multivariate analysis of variance ( manova ) to test whether there are differences between the means ofidenti ed groups of subjects on a combination of dependent variables. Forexample, in the paper above, the authors test whether the mean score of twogroups, graduates and diplomates, is the same across eight constructssimultaneously. Thus, they are considering eight dependent variables andcomparing the mean of this combination for two ' lambda performs, in the multivariate setting, with a combination ofdependent variables, the same role as theF-test performs in one-way analysisof variance . wilks ' lambda is a direct measure of the proportion of variance inthe combination of dependent variables that is unaccounted for by theindependent variable (the grouping variable or factor).
