PhipMeasure {CompExpDes} | R Documentation |
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.
PhipMeasure(design,p=15,q=2)
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. |
