Estimate a Delay Distribution

Source: R/estimate_delay.R
estimate_delay.Rd

[Maturing] Estimate a log normal delay distribution from a vector of integer delays. Currently this function is a simple wrapper for bootstrapped_dist_fit().

Usage

estimate_delay(delays, ...)

Arguments

delays

Integer vector of delays

...

Arguments to pass to internal methods.

Value

A <dist_spec> summarising the bootstrapped distribution

See also

bootstrapped_dist_fit()

Examples

# \donttest{
delays <- rlnorm(500, log(5), 1)
estimate_delay(delays, samples = 1000, bootstraps = 10)
