Geometrically designed variable knot splines in generalized (non-)linear models

作者:

Highlights:

• We propose an extension/generalization of the GeDS methodology, recently developed by Kaishev et al. (2016) for the Normal univariate spline regression case.

• To the more general GNM/GLM context.

• To the multivariate case of more than one independent variable.

• An extensive comparison of GeDS with major existing spline fitting methodologies is presented.

• The proposed generalized GeDS methodology is implemented in an R package, named GeDS, which is available from the Comprehensive R Archive Network (CRAN) at http://CRAN.R-project.org/package=GeDS.
