Hello

I am trying to use a Sheffe Cubic formula ( available through JMP macros) for regressing two continuous predictors against a continuous response. My unit of analysis is small data set 40 records...

The output shows me everything (including a significant anova and significant parameters) except a value of R square and R  adjusted. Is this a sign that the model is not valid OR a sigh of inability to complete the analysis due to my small data set OR something else?

My next step after this was to bootstrap the confidence intervals...but with an incomplete output I am kind of stuck...

Thank you very much in advance for your valuable feedback
