Description

Evaluate the smallest cononical correlation (ccor) coefficients or trace statistic between two matrices, where a larger ccor or trace statistic is better.

Usage

measurefun(hH, H, type=c('trace_statistic','ccor'))

Value

return a real number.

Arguments

hH

a n-by-q matrix, the estimated matrix.

H

a n-by-q matrix, the true matrix.

type

a character taking value within c('trace_statistic','ccor'), default as 'trace_statistic'.
