Description

Computes a second partial derivative of a smooth supersaturated model at a design point. Used in the computation of distance measures based on local smoothness.

Usage

1
partial.deriv.ssm(indices, ssm)

Arguments

indices

A vector of integers specifying the two variables by which we take the partial derivatives with respect to.

ssm

An SSM object.

Value

A single column vector containing the second partial derivatives with respect to the requested variables, evaluated at all design points.
