The results of exploratory data analysis is shown below:
1. Time series of observation(S)
The time series plot of total counts of services delivered per day across all places, (Sd) over and 11 year period is shown in the figure below. A rolling 10 day mean of Sd is also generated. The sharp jump in service volumes in the last year (May 13, 2021 to May 12, 2022) was unexpected. As discussed in the Limitations section in this paper, I dropped the 1 year period and used data until May 12, 2021.
