time_recompose {anomalize}

Recompose bands separating anomalies from "normal" observations

Description

Recompose bands separating anomalies from "normal" observations

Usage

time_recompose(data)

Arguments

data

A tibble or tbl_time object that has been processed with time_decompose() and anomalize().

Details

The time_recompose() function is used to generate bands around the "normal" levels of observed values. The function uses the remainder_l1 and remainder_l2 levels produced during the anomalize() step and the season and trend/median_spans values from the time_decompose() step to reconstruct bands around the normal values.

The following key names are required: observed:remainder from the time_decompose() step and remainder_l1 and remainder_l2 from the anomalize() step.

Value

Returns a tbl_time object.
