Where is the Zero-Inflated Poisson Regression Option in JMP 16?

CentroidMarmot1 — Sat, 10 Jun 2023 20:53:02 GMT

In JMP 16, it does not appear possible to follow the Zero-Inflated Poisson Regression Example tutorial instructions. Some of the tool options it says to use do not exist.

The following issues exist within the tutorial instructions :

6.From the Personality list, select Generalized Regression. There is only Generalized Linear Model

7.From the Distribution list, select ZI Poisson. There is no ZI Poisson, only "Poisson" (Link Function defaults to "Log")

If I run Generalized Linear Model with Poisson Distribution and check mark the "Overdispersion Tests and Intervals". The output does not look at all like the output of the tutorial (even with Overdispersion unchecked).

How do I successfully complete a Zero-inflated Poisson on JMP 16.0.0?

It is a JMP Pro feature.

Generalized Linear Model has Poisson as a distribution function.

Generalized regression, which is in JMP Pro, includes zero-inflated Poisson as an option.

Hi Byron_JMP! Thanks for your response. I must be confused, I am using "JMP Pro 16.0.0" (see screenshot in original post) but in my dropdown menu for there is only "Generalized Linear Model". I am trying to complete the tutorial because the tutorial is similar to my data--they are both zero-inflated.

How do I go about completing the tutorial and/or running a zero-inflated poisson using JMP without the generalized regression option?

Thank you Craige_Hales! I thought I had the Pro version as all my headers say "JMP Pro" see original screen shot but it does not provide me with the additional tools in your screenshot.

Seems there is something wrong with your installation. My suggestion is to contact your school software administration to see whether you have received correct installation instruction. A second option is to contact JMP Tech Support support@jmp.com
