Introduction to the Fit Model Platform<br />

Creating Linear Models<br />

The Fit Model platform constructs linear models that can have complex effects. You can select from the<br />

following fitting personalities:<br />

• St<strong>and</strong>ard least squares fit one or more continuous responses (multiple regression)<br />

• Stepwise regression selects important model effects<br />

• <strong>Multivariate</strong> analysis of variance (MANOVA) for multiple continuous responses<br />

• Loglinear variance fits both means <strong>and</strong> variances<br />

• Logistic regression for nominal or ordinal responses<br />

• Proportional hazard <strong>and</strong> parametric survival fits for censored survival data<br />

• Generalized linear models for various distributions <strong>and</strong> link functions<br />
