reg.est: Estimate the optimal dimension in linear regression problem

In freqdom: Frequency Domain Analysis for Multivariate Time Series

Description

Estimate regression operator P (matrix d \times d) in model

Y_t = P X_t + \varepsilon_t,

where X_t is a d-dimensional stationary process and \varepsilon_t forms a white noise.

Usage

reg.est(X, Y, K = NULL, Kconst = 1)

Arguments

X	regressors process
Y	response process
K	how many directions should be inverted (as in pseudoinverse)
Kconst	constant for heuristic (as in reg.dim.est)

Value

Estimated regression operator
