Description

This is necessary to calculate the SURE for higher-order spectral estimators.

Usage

1
get_c(X)

Arguments

X

An array of numerics. The data.

Details

this function only calculates C and the HOSVD so that calculating SURE is faster when doing it over and over again

Value

C_array An array of numerics. The "C" array from Gerard and Hoff (2015).

hosvd_x A list containing the higher-order SVD of X.

Author(s)
