MMASE: MMASE - Multivariate Mean Absolute Scaled Error

In jdestefani/MEMTS: Multivariate Error Measures for Time Series forecasting

Description

Computes the multivariate MASE as a mean of the MASEs of the individual time series

Usage

MMASE(X, X_hat)

Arguments

X	Target matrix (hxk) for k variables and forecasting horizon h
X_hat	Predicted matrix (hxk) for k variables and forecasting horizon h

Value

List containing:

• values_vec: Vector of the individual MASEs

• mean: Mean of the vector of the individual MASEs

Examples

X <- matrix(rnorm(100),10,10)
X_hat <- matrix(rnorm(100,mean=1),10,10)
results_list <- MMASE(X,X_hat)
results_list$values_vec # For individual MASEs vector
results_list$mean # For the mean of the individual MASEs vector
