Say I’m going to test across both cold and warm weather. There are certain factors and levels that I cannot test during a particular season. Other factors and levels that I have no interest in testing during a particular season (but it would not damage anything). Assume I can estimate cold season as being the first half of my test, how do I control the design? I don’t think I can set season as a blocking factor, as JMP doesn’t let me disallow factor-levels where design . has blocking. Thanks!
