PhipMeasure {CompExpDes}

Phi_p criterion

Description

For a given design Phi_p criterion is calculated. It is based on Morris and Mitchell (1995). When the designs are not in [0,1]^d form, lesser the value of Phi_p criterion better it is.

Usage

PhipMeasure(design,p=15,q=2)

Arguments

design

A design matrix is needed

p

Any positive integer. Default value of p = 15.

q

Any positive integer. Default value of q = 2. This implies that we are considering here Euclidean distance.

Value

Generates Phi_p criterion value
