The Logistic w Loss.jmp data table in the Nonlinear Examples sample data folder has an example for fitting a logistic regression using a loss function. The Y column contains ones for events and zeros for nonevents. The Model Y column has the linear model, and the Loss column has the loss function. In this example, the loss function is the negative loglikelihood for each observation, or the negative log of the probability of getting the observed response.
