Use scoringutils/mcs R package for statistical test of scores #109
Description
- Scoringutils has an option for pairwise comparison that should work in this case because we are using them same set of forecast dates and locations (ww vs hosp)
- mcs R package should also work and return the maximum set of distinguishable forecasts from the null hypothesis that all models perform the same (so could run this with the ARIMA + ww + hosp only)
