• Response Screening - Multiple model effects?

  I am trying to analyze a medium / large proteomics dataset (3350 proteins) using the response screening analysis.  The problem is that I have multiple model effects to take into consideration - I have treatment vs control, but I also have samples from multiple days to consider, but I clearly can't run this as a fit model.   Is it possible to take both treatment and day into consideration using JMP...

• Why is my Decision Tree have duplicate attributes in the same branch?

  Hi all. Just wondering if anybody knows why the decision tree is (in the case below) selecting Nozzle Air Pressure >42.09, then appears to contradict itself in the next node by selecting and splitting the Nozzle Air Pressure again? My understanding is that once an attribute is split, it should no longer be considered in subsequent branches. I'm using 10-fold cross validation with a holdback of 30%...

• When there is no interaction, can I use multiple comparison such as LSD or Tukey test?

  I have three factors - Genotype (5 levels), Nitrogen (2 levels), and manipulation (2 levels). I'm interested in the combination of three factors. I'd like to check how average grain weight responds to defoliation under the different nitrogen conditions. When I analyze it as the full factorial, there was no interaction among genotype x nitrogen x manipulation.  However, I want to indicate the diffe...

• trailing cumulative sum formula

  I have what is likely to be a very easy formula need. I have a temperature dataset and need to calculate a trailing cumulative sum over the past 120 days (known as "degree-heating weeks" since I will convert this sum to weeks by dividing by 7). I know how to get a trailing average, and I know how to get a cumulative sum, but is it possible to get a trailing, 120-day cumulative sum? In this case, w...
