transform11 {SSM}

Transform a design to [-1, 1]^d

Description

This function transforms a design (supplied as a matrix) into the space [-1, 1]^d. This has numerical and computational advantages when using smooth supersaturated models and is assumed by the default fit.ssm behaviour.

Usage

transform11(design)

Arguments

design

A matrix where each row is a design point.

Value

A matrix where each column contains values in [-1, 1]^d.

Examples

X <- transform11(quakes[, 1:4])
apply(X, 2, range)
