wtLHDs_prime function

Weighted Criteria-Based Latin Hypercube Designs (LHDs) for Prime Numbers

For prime number of factors, F (>2), this method will generate LHDs with levels, L ranges from F to F^2. Maxpro criterion measure, Phi_p measure also provided as a measure of space-filling and also as an orthogonality measure maximum absolute correlation (MAC) value also provided.

wtLHDs_prime(levels,factors,weights,iterations)

Arguments

• levels: L,ranges from F to F^2
• factors: A prime number, F (>2)
• weights: Weight should be given to Maxpro, Phi_p and MAC such that sum is 1. Default it is 0.2, 0.4 and 0.4
• iterations: Number of iterations. By default it is 300.

Returns

This function will provide a series of weighted criteria-based LHDs along with space-filling and orthogonality measures for the generated LHDs.
