Notes: Time period – May 15, to November 30. P-values from standard clustering by PHU (Stata command ‘cluster’) in the () parentheses, wild bootstrap with one-way clustering by PHU and 5000 repetitions in the [ ] square brackets, and wild bootstrap with two-way clustering by PHU and day with 5000 repetitions in the { } curly braces. PC denotes provincial total cases. ***, ** and * denote 10%, 5% and 1% significance level respectively.
