GPA: Generalised Procrustes Analysis of configurations
In provenance: Statistical Toolbox for Sedimentary Provenance Analysis
GPA R Documentation
Generalised Procrustes Analysis of configurations
Description
Given a number of (2D) configurations, this function uses a
combination of transformations (reflections, rotations,
translations and scaling) to find a ‘consensus’ configuration which
best matches all the component configurations in a least-squares
sense.
Usage
GPA(X, scale = TRUE)
Arguments
X
a list of dissimilarity matrices
scale
boolean flag indicating if the transformation should
include the scaling operation
Value
a two column vector with the coordinates of the group
configuration
