This dialog lets you specify output and options for fitting a standard curve with correlated errors. You can also request that no constant term is included in the model: this will affect only the parameterization of factor effects, if there are factors in the model; but if not, it will constrain the regression to pass through the origin.

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.
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.
A variate that can be used to allow data units to have unequal weights.
Maximum iterations to estimate phi
Specifies the maximum number of iterations (default 100) used to estimate phi.
