which approach is the best for demonstrating a change between growth curves? which approach would demonstrate a difference in growth over time which approach best illustrates the difference between a linear model and a mixed-effects model how to demonstrate a difference in growth curves what kind of data for a linear model how to demonstrate a difference in growth over time can you demonstrate the difference in growth over time which linear model would best be justified why is this approach to modeling useful can grofit and anova be justified can you show a difference in data for a grofit? which approach would you use to demonstrate the difference between a linear and a multilevel model? what approach do you use to test for a variance over time which approach to the test of growth curves which method is best to demonstrate a difference in growth over time what is the best approach to demonstrate the difference in the growth curves why do aNOVAs work? why is an anova necessary how to demonstrate differences in growth curve why is it difficult to demonstrate the difference in growth curves
