In multivarious: Extensible Data Structures for Multivariate Analysis

Compute reconstruction-based error metrics

Description

Given two numeric matrices Xtrue and Xrec, compute:

• MSE ("mse")

• RMSE ("rmse")

• R^2 ("r2")

• MAE ("mae")

Usage

measure_reconstruction_error(
  Xtrue,
  Xrec,
  metrics = c("mse", "rmse", "r2"),
  by_column = FALSE
)

Arguments

Xtrue	Original data matrix, shape (n x p).
Xrec	Reconstructed data matrix, shape (n x p).
metrics	Character vector of metric names, e.g. c("mse","rmse","r2","mae").
by_column	Logical, if TRUE calculate R2 metric per column and average (default: FALSE).

Value

A one-row tibble with columns matching metrics.
