Using shift_level_max() function in time series – R

Issue

This Content is from Stack Overflow. Question asked by Aaron

When I use shift_level_max() to find the largest mean shift between two consecutive sliding windows of the time series.

data("AirPassengers")
air.ts <- AirPassengers

library(feasts)
shift_level_max(air.ts)

The output is following:

  shift_level_max shift_level_index 
             62.6             127.0

could you tell me what shift_level_index (127) means? Or which period is it in the data?
