Dear Pakawadee,

❝ ^^ Does it mean that I need to recalculate F-value of sequence effect by myself, when I run R program for BE? Does it have any way to directly get a right result for sequence by running the program?

R's anova default is to give you type I sums of squares with all terms tested against the residual model variation. Therefore, if you use plain R, you will have to test the sequence effect against the proper between-subject term manually. Also, if your dataset is unbalanced you will notice a slight discordance with the power to know's results as they by default are created with type III sums of squares.

Best regards
EM.
