Description Usage Arguments Value Author(s) Source Examples
Estimate Covid19 outcome probabilities including hospitalizion|infection, ICU|hospitalization, death|hospitalization, and death|infection, using age-specific outcomes estimates of Pr(Clinical|Infection) from Davies et al. (2020) (with confidence intervals) and point estimates of Pr(hospitalization|clinical), Pr(ICU|hospitalization), and Pr(dead|hospitalization) from Van Zandvoort et al. (2020).
Population age distributions can either be taken from the UN World Population Prospects 2019 (WPP2019), or directly supplied by the user.

Either an ISO3 country code used to extract age-specific population estimates from the UN World Population Prospects 2019 dataset, or, a data.frame containing age categories in the first column and population counts (or proportions) in the second column |
p_type |
Outcome to estimate (either "p_hosp_inf", "p_icu_hosp", "p_dead_hosp", or "p_dead_inf") |
p_stat |
Statistic of the severity estimates to use (either "mean", "median", "low_95", "up_95", "low_50", or "up_50") |
Estimated outcome probability (scalar)
