PhipMeasure {CompExpDes} | R Documentation |
Phi_p criterion
Description
For a given design Phi_p criterion (Morris and Mitchell, 1995) is calculated using this function. Lesser the value of Phi_p criterion better the design in terms of space-filling.
Usage
PhipMeasure(design,p=15,q=1)
Arguments
design |
A design matrix is needed |
p |
Any positive integer. Default value of p = 15. |
q |
Any positive integer. Default value of q = 1. This implies that we are considering here Euclidean distance. |
Value
Generates Phi_p criterion value
