Test_aSPA: Test average Superior Predictive Ability

In MultiHorizonSPA: Multi Horizon Superior Predictive Ability

Description

Implements the test for average Superior Predictive Ability (aSPA) of Quaedvlieg (2021)

Usage

Test_aSPA(LossDiff, weights, L, B = 999)

Arguments

LossDiff	the T x H matrix forecast path loss differential
weights	the 1 x H vector of weights for the losses at different horizons. For instance weights <- matlab::ones(1,20)/20
L	integer, the parameter for the moving block bootstrap
B	integer, the number of bootstrap iterations. Default 999

Value

A list containing two objects:

"p_value"	the p-value for aSPA
"t_aSPA"	the statistics for aSPA
