In GPAbin: Unifying Multiple Biplot Visualisations into a Single Display

Orthogonal Procrustes Analysis

Description

This function performs Orthogonal Procrustes Analysis on centred data

Usage

OPA(missbp, compdat, centring = TRUE, dim = "2D")

Arguments

missbp	An object of class missmi obtained from preceding function missmi()
compdat	Complete data set, only available for simulated data examples.
centring	Logical argument to apply centering, default is TRUE.
dim	Number of dimensions to use in final solutions (⁠2D⁠ or All available dimensions.)

Value

ProcStat	Procrustes Statistic
compZ	Sample coordinates representing the complete data set
compCLP	Category level point coordinates representing the complete data set
complvls	Category levels
compdat	Complete data set, only available for simulated data examples
