align_pcdirs: Obtain PC directions with centered warping functions

In veesa: Pipeline for Explainable Machine Learning with Functional Data

Obtain PC directions with centered warping functions

Description

The function 'prep_training_data' does not center the warping functions, which leads to issues when visualizing joint and horizontal principal component directions. This function aligns the principal directions for improved interpretability of the principal directions. Currently, only alignment for jfPCA has been implemented.

Usage

align_pcdirs(train_obj)

align_pcdirs(train_obj)

Arguments

train_obj

Output object from 'prep_training_data' (jfpca only)

Value

List with the same structure as 'prep_training_data', but the principal directions are replaced with the aligned version and gamI is included in the fpca_res object.
