PolyOrdinalLogBiplot function

Factor Analysis Biplot based on polychoric correlations

Calculates a biplot for ordinal data based on polychoric correlations

PolyOrdinalLogBiplot(X, dimension = 3, method = "principal", 
rotate = "varimax", RescaleCoordinates = TRUE, ...)

Arguments

• X: A matrix of ordinal data
• dimension: Number of dimensiona to retain
• method: Principal components (principal) or factor analysis (fa)
• rotate: Rotation for the analysis
• RescaleCoordinates: Rescale coordinates as in a continuous data biplot
• ...: Any aditional arguments for the principal and fa functions

Details

The procedure calculates

Returns

A biplot (Continuous or ordinal)
