is homogeneity necessary for changepoint analysis is homogeneity of variance required does the experiment require homogeneity of variance why is it necessary to use the pelt method in a changepoint analysis does the paradigm method require equal variance what is required for a changepoint what assumption of equal variance is required for a changepoint analysis? does changepoint analysis have equal variance before and after the changepoint? is homogeneity required for changepoint analysis? what is the purpose of a changepoint analysis? how does the pelt method determine the underlying variance what type of variance is required in a changepoint analysis? which is the assumption of equality of variance when using the pent method? is homogeneity of variance important in changepoint analysis is homogeneity required for changepoint analysis what is the purpose of the pret method can the pelt method be used to perform a changepoint analysis? is homogeneity required for changepoint analysis do you need to assume homogeneity of variance to perform changepoint analysis when to use the pelt method? what type of variance is required for changepoint analysis
