Prediction conciliation by projection.

Share:

Description

Uses a simple L2 projection to reconciliate hierarchical time series forecasts.

Usage

1
proj(preds_indiv, pred_total, weights_indiv, weight_total)

Arguments

preds_indiv

: K-length vector with predictions ybar_1,...,ybar_K for individual regions

pred_total

: number with prediction ybar_* for the total consumption

weights_indiv

: K-length vector with weights a_1,...,a_K for individual regions

weight_total

: number with weight a_* for the total consumption

Value

A vector with the reconciliated predictions for the individuals and the total.

Examples

1
2
3
4
K <- 5
proj(preds_indiv = rep(0, K), 1,
     weights_indiv = rep(1, K),
     weight_total = 2)
