freeknotsplines: Free-Knot Splines

Description Details Author(s) References

Description

This package is for fitting free-knot splines for data with one independent variable and one dependent variable.

Details

Four fitting methods are included for the case where the number of knots is known in advance; for details, see freeknotfit. In addition, methods are available to compute the fitted values, the residuals, and the coefficients of the splines, and to plot the results, along with a method to summarize the results. Finally, a function (see fit.search.numknots) is provided to optimize the number of knots using a specified fit criterion. Several fit criteria are provided (see fitcriteria).
