In epiparameter: Classes and Helper Functions for Working with Epidemiological Parameters

Optimises the parameters for a specified probability distribution given the percentiles of a distribution and the values at those percentiles, or the median and range of a sample and the number of samples.

Description

Optimises the parameters for a specified probability distribution given the percentiles of a distribution and the values at those percentiles, or the median and range of a sample and the number of samples.

Usage

.extract_param(values, distribution, percentiles, samples)

Arguments

values	A vector. If type = percentiles: c(percentile_1, percentile_2); and if type = range: c(median, min, max).
distribution	A character specifying distribution to use. Default is lnorm; also takes gamma, weibull and norm.
percentiles	A vector with two elements specifying the percentiles defined in values if using type = "percentiles". Percentiles should be specified between 0 and 1. For example 2.5th and 97.5th percentile is given as c(0.025, 0.975).
samples	A numeric specifying the sample size if using type = "range".

Value

A list with output from stats::optim().
