See Selecting a Custom Equation Fit Interactively. Selecting a Linear Fitting Custom Fit Interactively In the Curve Fitter app, select some curve data. On the Curve Fitter tab, in the Data section, click Select Data. In the Select Fitting Data dialog box, select X data and Y data values. ...
If there are k independent variables, there are 2k possible linear equations to be examined; one equation using none of the variables, k using one variable, k(k 1)/2 using two variables, etc. Often there are several equally good candidates. Selection depends on whether one needs a simple ...
A New Method of Interpolation and Smooth Curve Fitting Based on Local Procedures A new mathematical method is developed for interpolation from a given set of data points in a plane and for fitting a smooth curve to the points. This method is devised in such a way that the resultant curve ...
