🧚 Does Loot Fairy Come Periodically in Wormholes?

Short story

If I count all wormhole regions, loot fairy slightly prefers to come every month. In some wormhole regions, loot fairy prefers to come every X days. But X is generally different for different regions.

Average of Regional Averages
|spectrum_all_wh
The spectrum shows periodic fluctuations in the amount of Isk lost by T1 exploration frigates.

time_series_all
The time series shows the normalized Isk lost over time.

Details

  • For every week, I calculate the normalized Isk lost in a region with two steps:
    1. I calculate (raw isk lost) = (Isk lost in this worm hole region) / [(#Ship killed in this region) * (Isk lost all the worm hole regions) ]
      This should remove the effect of inflation and account for the regional differences of the amount of ships killed.
    2. Standardize the (raw isk lost) over all weeks. I subtract the average over time from all the (raw isk lost). Then I divide the result by the standard deviation.
      This would make all the spectra for all regions have similar magnitudes.
  • The average of regional average is: average of normalized Isk lost over all regions.
    Notice that this give all regions equal importance. The regions don’t have the same number of systems.
  • The data is from the monthly economic reports and a kill dump for March, 2016.
  • I group kills every 7 days to remove the strong weekly cycle.

Have you sacrificed a ship at the sun to appease Bob?

And what is the conclusion?

“Does Loot Fairy Come Periodically in Wormholes?”

You gotta ask Bob about that … ( ͡° ͜ʖ ͡° )
