Hello Steve, Thanks for the reply. To be more precise I have observation A within three years. The number of observations are same i.e. 100 within all three years. -First year has one location where observations were taken and replicates in that year are 6. -Second year has one location but 3 replicates -Third year has two locations and 3 replicates per location Can you please help me if I want to check homogeneity of variance, ANOVA and heritability on SAS how can I perform it? Thanks
