Statistical methods provide a powerful set of tools to better understand infectious diseases. This chapter discusses the use of statistical methods to better understand transmission dynamics, infectiousness, key intervals, and severity. Specifically, methods for handling data from household studies are introduced, as well as statistical approaches to estimating the reproductive number. In addition, the chapter describes approaches to estimate key intervals, such as the serial interval and generation interval, while accounting for truncation, censoring, and the discreteness of observed data. Estimates of severity, such as the case fatality ratio, are introduced with approaches to account for unobserved cases and fatalities.
