What inspired this wish list request? JMP does not seem to have built-in support for zero-inflated models? We have to use another statistical software like R or Python to fit zero-inflated models.
What is the improvement you would like to see?
Why is this idea important? These models are used when the response variable has a large number of zero values and a continuous, non-negative distribution for the non-zero values. Zero-inflated models combine two separate models: one for predicting the probability of a zero outcome, and another for predicting the non-zero values.
