CCA: Canonical Correlation Estimation

Description

Canonical Correlation Estimation

Usage

CCA(y, rmax = 8, r0 = NULL, r = NULL, localfactor = FALSE, method = "CCD", type = "IC3")

Value

r0hat

the estimated number of the global factors.

rho

the estimated number of the local factors.

Ghat

the estimated global factors.

Fhat

the estimated local factors.

loading_G

a list consisting of the estimated global factor loadings.

loading_F

a list consisting of the estimated local factor loadings.

e

a list consisting of the residuals.

threshold

the threshold used in determining the number of global factors, only for method = "MCC".

Arguments

y

a list of the observation data, each element is a data matrix of each group with dimension \(T * N_m\).

rmax

the maximum factor numbers of all groups.

r0

the number of global factors, default is NULL, the algorithm will automatically estimate the number of global factors. If you have the prior information about the true number of global factors, you can set it by your own.

r

the number of local factors in each group, default is NULL, the algorithm will automatically estimate the number of local factors. If you have the prior information about the true number of local factors, you can set it by your own, notice it should be an integer vector of length \(M\) (the number of groups).

localfactor

if localfactor = FALSE, then we would not estimate the local factors; if localfactor = TRUE, then we will further estimate the local factors.

method

the method used in the algorithm, default is CCD, it can also be MCC.

type

the method used in estimating the factor numbers in each group initially, default is IC3.
