chris_interval_intersect: Calculate the interval intersect (Chris' code).

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 the interval intersect used in the calculation of the intergral for the infection likelihood. This is the interval [ (R_i ^ I_j) - (I_i ^ I_j) ] for i in infecteds and j in all.

Usage

chris_interval_intersect(interval_i, interval_j)

Arguments

interval_i	Is the matrix cbind(t_inf, t_rem)[infected, ]. This is a 2 column matrix of the infection and removal times for the infected individuals.
interval_j	Is the matrix cbind(t_inf, t_rem). This is a 2 column matrix of the infection and removal times for all individuals.

Value

Returns a matrix where each column is a vector for each j.

Examples

This function is utilised by the log_likelihood function.
