IndepTest (version 0.2.0)

MINTknown: MINTknown

Description

Performs an independence test when it is assumed that the marginal distribution of \(Y\) is known and can be simulated from.

Usage

MINTknown(x, y, k, ky, w = FALSE, wy = FALSE, y0)

Arguments

x

The \(n \times d_X\) data matrix of \(X\) values.

y

The \(n \times d_Y\) data matrix of \(Y\) values.

k

The value of \(k\) to be used for estimation of the joint entropy \(H(X,Y)\).

ky

The value of \(k\) to be used for estimation of the marginal entropy \(H(Y)\).

w

The weight vector to used for estimation of the joint entropy \(H(X,Y)\), with the same options as for the KLentropy function.

wy

The weight vector to used for estimation of the marginal entropy \(H(Y)\), with the same options as for the KLentropy function.

y0

The data matrix of simulated \(Y\) values.

Value

The \(p\)-value corresponding the independence test carried out.
