Purpose

Create plot of permutation test results.

Synopsis

fig = permuteplot(results,nlvs);

Description

Produces a plot of fractional y-block information captured by calibration and cross-validation versus y-correlation is shown. The x-axis of this figure shows the correlation of each permuted y-block against the original. The y-axis shows the fractional information captured (1 - RMS(E).^2 / RMS(Y).^2). The plot includes the unperturbed results too. A significant difference between the unperturbed and permuted y-block results indicates the likelihood of original model significance.

Inputs

  • results = Results structure from permutetest.

Optional Inputs

  • nlvs = Number of latent variables for which results should be shown.

Outputs

  • fig = Handle of the created figure.
