SAS JMP: Mixed Step wise SelectionHi,
Can I run Mixed Step Wise Selection on SAS JMP and if yes can this be done if my dependent variable is categorical?.
Re: SAS JMP: Mixed Step wise SelectionHard to say, given so little information.
- What is the nature of your response? Ordinal? Nominal? Number of levels?
- Does your response exhibit a separation problems with any of the predictors?
- How many predictors?
- Did you try to fit the same model with Nominal Logistic or Ordinal Logistic already? Do you get the same error?
You might need to send your case to support@jmp.com for help.
