In hlplab/MVBeliefUpdatr: Fitting, Summarizing, and Visualizing of Multivariate Gaussian Ideal Observers and Adaptors

Transform and untransform category means and covariance matrices of a model

Description

Applies the transformation specified in transform object (e.g., centering, scaling, PCA) to the category mean(s) and/or covariance(s) in the model.

Usage

transform_model(model, transform)

untransform_model(model, transform)

transform_category_mean(m, transform)

untransform_category_mean(m, transform)

transform_category_cov(S, transform)

untransform_category_cov(S, transform)

Arguments

model	A model with columns that specify category means (mu or m) and covariance information (Sigma or S).
transform	A transform or transform parameter object of the type returned by transform_cues.
m	A single category mean or alike.
S	A single covariance matrix or alike.

Value

A model, category mean, or covariance matrix of the same type as the input.
