Fitting Menu Options<br />

The following table describes the options in the Fitting menus.<br />

Confid Curves Fit<br />

Confid Curves Indiv<br />

Displays or hides the confidence limits for the expected value (mean).<br />

This option is not available for the Fit Spline, Density Ellipse, Fit Each<br />

Value, <strong>and</strong> Fit Orthogonal fits <strong>and</strong> is dimmed on those menus.<br />

Displays or hides the confidence limits for an individual predicted<br />

value. The confidence limits reflect variation in the error <strong>and</strong> variation<br />

in the parameter estimates. This option is not available for the Fit<br />

Mean, Fit Spline, Density Ellipse, Fit Each Value, <strong>and</strong> Fit Orthogonal<br />

fits <strong>and</strong> is dimmed on those menus.<br />

Lets you select from a palette of colors for assigning a color to each fit.<br />

Displays or hides the line of fit.
