translink_expected_links_true_mtml {phylosamp}

Calculate expected number of true transmission pairs assuming multiple-transmission and multiple-linkage

Description

This function calculates the expected number of true transmission pairs in a sample of size M. The multiple-transmission and multiple-linkage method assumes the following:

1. Each case i is, on average, the infector of R cases in the population (N)

2. Each case i is allowed to be linked by the linkage criteria to multiple cases j in the sampled population (M).

3. Linkage events are independent of one another (i.e, linkage of case i to case j has no bearing on linkage of case i to any other sample).

Usage

translink_expected_links_true_mtml(sensitivity, rho, M, R)

Arguments

sensitivity

scalar or vector giving the sensitivity of the linkage criteria

rho

scalar or vector giving the proportion of the final outbreak size that is sampled

M

scalar or vector giving the number of cases sampled

R

scalar or vector giving the effective reproductive number of the pathogen

Value

scalar or vector giving the expected number of true transmission pairs in the sample
