I want to perform a MANOVA in SPSS as follows: i have a independent variable that consists of three groups (- of which the group sizes are not equal), and six dependent variables. When checking the Levenes test for equality of error variances To test this assumption, use Levenes homogeneity-of-variance test, available in the One-Way ANOVA procedure.For the difference in means: mean, standard error, and condence interval (you can specify the condence level). Tests: Levenes test for equality of variances and both The SAS TTEST procedure and SPSS T-TEST command conduct F tests for equal variance. SAS reports the folded form F statistic, whereas SPSS computes Levenes weighted F statistic.LSDV1 produces correct ANOVA information, goodness of fit, parameter estimates, and standard errors. Purpose: Test for Homogeneity of Variances. Levenes test ( Levene 1960) is used to test if k samples have equal variances.Some statistical tests, for example the analysis of variance, assume that variances are equal across groups or samples. If the error variances equality is the same as population variances equality, how can I justify using the results from the analysis?Tags : anova variance levenes-test two-way.
