WebANOVA on ranks. In statistics, one purpose for the analysis of variance (ANOVA) is to analyze differences in means between groups. The test statistic, F, assumes independence of observations, homogeneous variances, and population normality. ANOVA on ranks is a statistic designed for situations when the normality assumption has been violated. Web11 de jul. de 2015 · As far as being interested in the "normality" it is my understanding that running a real valid or robust linear regression or ancova depends on my data being normally distributed and having equal variance. Also, I'm more interested in being able to compute confidence limits on my weighted means (hence the prop.test). -Thanks –
