Description Usage Arguments Note

View source: R/helper_functions.R

Description

Given input points in d dimensions, construct a low-rank thin plate spline basis matrix and penalty matrix.

Usage

1
getSplineInfo_d(tau, m_eff = NULL, orthonormalize = TRUE)

Arguments

tau

m x d matrix of coordinates, where m is the number of observation points and d is the dimension

m_eff

the effective number of observation points; (e.g., the median number of observation points when missing observations)

orthonormalize

logical; if TRUE, orthornomalize the basis matrix

Note

The knot locations are selected using a space-filling algorithm.
