maximin.remove {SFDesign} | R Documentation |
Sequentially remove design points from a design while maintaining low reciprocal distance criterion as possible
Description
This function sequentially removes design points one-at-a-time from a design while maintaining low reciprocal distance criterion as possible.
Usage
maximin.remove(D, n.remove, r = 2 * p)
Arguments
D |
the design matrix. |
n.remove |
number of design points to remove. |
r |
the power parameter in the |
Details
maximin.remove
sequentially removes design points from a design in a greedy way while maintaining low reciprocal distance criterion (see maximin.crit
) as possible. In each iteration, the design point with the largest sum of reciprocal distances with the other design points is removed, that is, k^* = \arg\max_k \sum_{i\neq k}\frac{1}{\|\bm x_k - \bm x_i\|^r}
.
Value
the updated design.
Examples
n = 20
p = 3
n.remove = 5
D = maximinLHD(n, p)$design
D = maximin.remove(D, n.remove)
