So I have some catagorical data where one category never shows up in the Parameter Estimates part of any analysis I try with this data (for example Generalized Linear Models, Nominal Logistic, and Ordinal Logistic). It is always the "highest/latest" catagory of the column (in my case Methods 3 or Cycle 5). Even when I Hide/Exclude the other categories these never show up. If I change another category's name so it is "higher/later", it dissapears instead (I change Methods 0 to Methods 4 for example).
Does anyone have any idea why this is happening and how to fix it?
I use JMP® 16.1.0 (539038) if that matters.
