Splines2.jl package for regression splines

A Julia package for regression splines. The package currently includes B-splines, natural B-splines, M-splines and I-splines.

News

Version 0.3.0

• Support for safe predictions in StatsModels.@formula for natural splines.
• Substantial refactoring of internal code to use callable types.

Version 0.2.0:

• Mainly bug fixes.
• A change of behaviour for Splines2.is_ and Splines2.is: intercept=true will include a columns of ones, while the default intercept=false will keep all of the spline terms, but exclude the column of ones. This behaviour is different to the splines2 package in R, which will give all of the spline terms for intercept=TRUE and drop the first spline term for intercept=FALSE.
