what test is used to check the assumption of homogeneity of regression slopes? what is aov which r function tests for homogeneity why is r test for homogeneity of regression what is the homogeneity test in r which is based on the assumption that there are aliased coefficients r test for homogeneity of regression slopes r test for homogeneity of regression slopes what test is the model for homogeneity of regression what is the difference between anova and anova in r/o? if a model has one dependent variable, does it need to be homogeneous in r which model is used with the homogeneity test what is the r test for homogeneity of regression slopes test for homogeneity of regression slope in singular model r test for homogeneity of regression slopes which variable can be used as an aliased coefficient for r r test for homogeneity of regression what is the assumption of r test for homogeneity how to check the assumption of homogeneity test for homogeneity of regression slopes in singular model
