prod_part: Calculate the product part of the infection likelihood

In IanniMuliterno/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

prod_part(inf_times, rem_times, B, infected_inds)

Arguments

inf_times	A vector of the infection times of all individuals (Inf if not infected).
rem_times	A vector of the removal times of all infected individuals.
B	The infection rate matrix.
infected_inds	A vector of the infected individuals.

Value

Returns the value of the product detailed above.

Examples

This function is utilised by the log_likelihood function.
