md_b {PPCI} | R Documentation |
Location of Minimum Density Hyperplane
Description
The value of b which minimises the penalised integrated density on the hyperplane H(v, b) = [x : v'x = b] (assumes the data have zero mean vector). If v is a locally optimal solution for the projection index f_md then H(v, b) is a locally optimal hyperplane.
Usage
md_b(v, X, P)
Arguments
v |
a numeric vector of length ncol(X) |
X |
a numeric matrix (num_data x num_dimensions) to be projected on v |
P |
a list of parameters including (at least) $h (positive numeric bandwidth value), $alpha (positive numeric constraint width), $C (positive numeric affecting the slope of the penalty) |
Value
the value of b given in the description.
