fit_unimix: Fit of Normal and Exponential-Normal Mixtures to Binned Data

In tpetzoldt/antibioticR: Analysis of Antibiotic Resistance Data

Description

Fit mixture distributions to binned data with a maximum likelihood method, inspired by Venables and Ripley (2002)

Usage

fit_unimix(
  breaks,
  counts,
  parms,
  type = c("en", "enn", "ennn", "ennnn", "ennnnn", "n", "nn", "nnn", "nnnn", "nnnnn"),
  sd_min = 0,
  ...
)

fit_n(breaks, counts, parms, sd_min = 0, ...)

fit_en(breaks, counts, parms, sd_min = 0, ...)

fit_nn(breaks, counts, parms, sd_min = 0, ...)

fit_enn(breaks, counts, parms, sd_min = 0, ...)

fit_nnn(breaks, counts, parms, sd_min = 0, ...)

fit_nnnn(breaks, counts, parms, sd_min = 0, ...)

fit_ennn(breaks, counts, parms, sd_min = 0, ...)

fit_ennnn(breaks, counts, parms, sd_min = 0, ...)

fit_nnnnn(breaks, counts, parms, sd_min = 0, ...)

fit_ennnnn(breaks, counts, parms, sd_min = 0, ...)

Arguments

breaks	upper class limits of the data
counts	frequency of observations
parms	list of initial parameters for the mixture
type	of the mixture distribution, e.g. 'enn' for exponential-normal-normal
sd_min	lower boundary value for standard deviation and rate parameter
...	additional arguments passed to mle2
