Predefined Fitting Models
Over 100 predefined fitting models are available.  They are grouped in several groups. The Special Multiple Linear Group can be accessed through menu commands.  The rest can be accessed through either the predefined fitting dialog box in the data sheet or the curve fitting command in the plot view.
Special Multiple Linear Group:

Model Equation


multiple linear model

multiple linear logistic model

multiple linear logistic model (exponential form)

Stepwised multiple model

stepwise multiple linear curve fitting is a sequential regression (curve fitting) process to select a multiple model. PSI-Plot (ProStat) provides the three commonly used methods: forward selection, backward elimination, and stepwise.
