Estimate Constant Term

Specifies whether to include a constant in the regression model. In simple linear regression this omits the intercept, in other words the fitted line is constrained to pass through the origin. In nonlinear regression (curve fitting) the constant term usually represents an asymptote, and omitting the constant fixes the asymptote at 0; to constrain the curve to pass through the origin you should set the Constrain Origin option.

Constrain Origin

Constrains a nonlinear regression to pass through the origin, i.e. to have a response of 0 for zero in the explanatory variate. This can only be used with exponential and rational curves.

Weights

A variate that can be used to allow data units to have unequal weights. The name of the variate can be entered into the space provided or double-clicked across from the list of available data.

Maximum iterations to estimate phi

Specifies the maximum number of iterations (default 100) used to estimate phi.
