Challenge library

EpiBenchmark ships with a library of predefined challenges (challenges have fixed hub, target, dates, horizons, quantiles, locations, and scoring requirements). Explore each challenge in our library below. You can list them locally via the command line with epibench list, and fully download a bundled challenge with epibench fetch <challenge-id>.
