gen_splines: B-spline basis generation

In hongqi0314/PRAuto.PMML: User defined functions to output a PMML file that is to be implemented in S1

Description

Generate the B-spline basis

Usage

gen_splines(x, limits, knots, missCode = NA, degree = 1, intercept = TRUE,
  name)

Arguments

x	Vector of numerical attribute that is going to be transformed to splines/hats.
limits	Vector of two float numbers indicating model fitting limits for x.
knots	Vector of float numbers representing inner cutpoints of x.
missCode	An integer indicating missing value, e.g. 0 or 999.
degree	An integer indicating degree of the transformed splines.
name	Character string used as the new field names for the transformed data.

Value

Data frame contains transformed splines. The returned data frame has 'length(knots) + degree (+ 1 if there is an intercept)' columns.

Examples

basisFICO <- gen_splines(x = Data_UsedPlat$FICO, limits = c(450, 900),
    knots = c(500, 525, 540, 575, 600, 670), degree = 3, missCode = 0, name = 'FICO')
