R: Procrustes and Partial Procrustes correlations.

procrustes.syncsa {SYNCSA} | R Documentation

## Procrustes and Partial Procrustes correlations.

### Description

Function to obtain the Procrustes correlation between two matrices and partial Procrustes correlation between three matrices.

### Usage

    procrustes.syncsa(x, y)

    procrustes.partial(x, y, z)

### Arguments

`x, y` | Matrix that will be correlated.
`z` | Matrix whose effect will be removed from the correlation between x and y.

### Details

The function procrustes.syncsa is a small change in the function `procrustes`. The function uses a correlation-like statistic derived from the symmetric Procrustes sum of squares. Partial Procrustes correlations is obtained by Procrustes correlation of residuals between each variable in z being used as linear predictor of all variables in x and y. For more details, see `syncsa`.

### Value

Procrustes correlation between matrices.
