chris_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

chris_prod_part(t_inf_j, events, B)

Arguments

t_inf_j	A vector of the infection times of all individuals (Inf if not infected), ordered by ID.
events	A 2 column matrix where the first column is the infection times, and the second is the paired removal times.
B	The infection rate matrix.

Value

Returns the value of the product detailed above.

Examples

This function is utilised by the chris_log_likelihood function.
