cfa.Czz: Compute the eigenvectors

Description

Compute the eigenvectors to the matrix of row profiles.

Usage

cfa.Czz(sym.data, TFilas, TColumnas, VPRealz, d)

Arguments

sym.data

Should be a symbolic data table read with the function read.sym.table(...).

TFilas

Value of the total sum of the rows of the matrix.

TColumnas

Value of the total sum of the columns of the matrix.

VPRealz

The output of the function cfa.CVPRealz.

d

Eigenvalues.

Value

• Return the eigenvectors.
