Fitting Linear Models

Model Specification

Specify Linear Models

The Fit Model platform enables you to specify a variety of complex models using different fitting techniques or personalities. This chapter focuses on elements that are common to most personalities.

Fit Model personalities enable you to fit the following types of models:

simple and multiple linear regression

analysis of variance and covariance

random effect, nested effect, mixed effect, repeated measures, and split plot models

nominal and ordinal logistic regression

multivariate analysis of variance (MANOVA)

canonical correlation and discriminant analysis

loglinear variance (to model the mean and the variance)

generalized linear models (GLM)

parametric survival and proportional hazards

response screening, for studying a large number of responses

Image shown hereIn JMP Pro, you can also fit the following models:

generalized regression models including the elastic net, lasso, and ridge regression

mixed models with a range of covariance structures

generalized linear mixed models (GLMM)

partial least squares
