Hi,

How to estimate the estimate trend is for which week of which year?

1. The following time plot shows a weekly peak electricity demand series for 12 years (consist of 624 observations) from week 1 of 2005 to week 52 of 2016. Assuming that the series has additive seasonality, answer each of the following questions: 18000 17000 Peak electricity demand (mw) 16000 15000 14000 13000 12000 11000 10000 9000 323 507 530 553 576 599 Week a) Explain how to estimate the trend component of this series using classical decomposition. The first value of estimate represents the estimate of trend for which week of which year
