simple_prod_part: Calculate the product part of the infection likelihood...

In BenjamenSimon/EpidemicR: Stochastic modelling and inference for epidemics.

Description

This function is used in the calculation of the likelihood for a General Stochastic Epidemic, and calculates ∏_{j != kappa}^{n_I} [ ∑_{ i in I_{n_{j-}} } [ beta_{i,j} ] ].

Usage

simple_prod_part(inf.times, rem.times, beta.mat)

Arguments

inf.times	A vector of the infection times of all individuals (Inf if not infected), ordered by ID.
rem.times	A vector of the removal times of all individuals (Inf if not infected), ordered by ID.
beta.mat	The infection rate matrix.

Value

Returns the value of the product detailed above.

Examples

This function is utilised by the simple_log_likelihood function.
