Purpose

Evolving factor analysis (forward and reverse)..

Synopsis

[egf,egr] = evolvfa(xdat,plots,tdat)

Description

EVOLVFA calculates the singular values (square roots of the eigenvalues of the covariance matrix) of sub-matrices of xdat and returns results of the forward analysis in egf and reverse analysis in egr.

[egf,egr] = evolvfa(xdat) calculates eigenvalues of sub-matrices of xdat and returns results of the forward analysis in egf and reverse analysis in egr.
[egf,egr] = evolvfa(xdat,plots) allows the user to control plotting options. When plots is set to 0 the plot of the results is suppressed. Setting plots equal to 1 {default} plots the results.
[egf,egr] = evolvfa(xdat,plots,tdat) gives the routine an optional vector tdat to plot results against.

Inputs

  • xdat = input x-block (2D), either a double array or dataset object

Optional Inputs

  • plots = [ 0 | {1} ] - 0 suppresses plotting
  • tdat = vector to plot results (egf and egr) against

Outputs

  • egf = results of forward analysis
  • egr = results of reverse analysis
