wilson_lower

the observed numbers of cases in the samples meeting the required condition; numeric vector; no default

the numbers of cases in the samples; numeric vector; no default

the required level of confidence expressed as a number between 0.9 and 1
or 90 and 100; numeric; default 0.95

confidence

Calculates lower confidence limits for observed numbers of events using the Wilson Score method [1,2].

Functions to calculate commonly used public health statistics and
their confidence intervals using methods approved for use in the production
of Public Health England indicators such as those presented via Fingertips
(<http://fingertips.phe.org.uk/>). It provides functions for the generation
of proportions, crude rates, means, directly standardised rates, indirectly
standardised rates, standardised mortality ratios, slope and relative index
of inequality and life expectancy.
