BasisCon: Basis Construction Function

In funstatpackages/GgAM: Generalized geoAdditive Models

Description

Smooth terms in a plbpsm formula are turned into smooth specification objects of class xx.smooth.spec during processing of the formula. Each of these objects is converted to a smooth object using an appropriate BasisCon function.

Usage

BasisCon(object, data)

Arguments

object	is a smooth specification object or a smooth object.
data	A data frame, model frame or list containing the values of the (named) covariates at which the smooth term is to be evaluated. If it’s a list then n must be supplied.

Details

It is the wrapper function which calls basis constructing method.

Value

a list of smooth objects are returned. Many of the outputs are from b function. Other outputs include all the information related to berstein basis.

Examples

library(BPST)
data("eg1pop_dat")
eg1_V2=eg1pop_dat[['V2']]
eg1_T2=eg1pop_dat[['T2']]
eg1pop_rho03=eg1pop_dat[['rho03']]
sam=eg1pop_rho03[sample(1:dim(eg1pop_rho03)[1],70),]

# bivariate spline
BI <- BasisCon(b(x1,x2,d=2,r=1,V=eg1_V2,Tr=eg1_T2),sam)
# univariate spline
BI <- BasisCon(u(z1),sam)
