In sbfnk/bpmodels: Simulating and Analysing Transmission Chain Statistics using Branching Process Models

Log-likelihood of the length of chains with generic offspring distribution

Description

The likelihoods are calculated with a crude approximation using simulated chains by linearly approximating any missing values in the empirical cumulative distribution function (ecdf).

Usage

offspring_ll(x, offspring, stat, nsim_offspring = 100, ...)

Arguments

x	vector of sizes
offspring	Offspring distribution: a character string corresponding to the R distribution function (e.g., "pois" for Poisson, where rpois is the R function to generate Poisson random numbers)
stat	statistic given as x ("size" or "length" of chains)
nsim_offspring	number of simulations of the offspring distribution for approximation the size/length distribution
...	any parameters to pass to chain_sim

Value

log-likelihood values
