Subject: Block factor as random or fixed effect?
People
I apologise for asking a general stats question, but I'm at a bit of a
loss as to what to do following some hostile referees' comments. If I
have a fully randomised blocked design, with only three blocks, should
I treat block as a random or fixed effect? I have read comments about
not treating block as a random effect if the number of blocks is less
than 6 or 7: is this right?
Any advice much appreciated
