Each drops one of the 20 collection dates, splits the remaining readings into an earlier half and a later half of equal size, takes the mean African share in each half, and reports the later half against the earlier half as a percentage change. as_published_change_pct does this on the denominator as published. excluding_india_change_pct does it on the denominator with India removed on every date. sign_flips is 1 where the two measures disagree about whether African share rose or fell over the window. The test asks whether any single collection date is carrying the reversal.","unit":"pct","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
