mainSimul: simulate many times the first model and calculate the risk...

In rhosp: Side Effect Risks in Hospital : Simulation and Estimation

Description

main simulates nbBed times the first model with the function simul and calculates the risk constant R and CR by solving the renewal equation (star). this renewal equation is only valid if the Xi forms a poisson process. R and CR are defined such that the equivalent survival function is CR *exp(-R*x).

Usage

mainSimul(nbBed, nbPatient, disXi, disP, toplot = FALSE, calc = TRUE)

Arguments

nbBed	the number of beds
nbPatient	the number of patient in each bed
disXi	the distribution of the variable Xi : disXi is a 3 elements list : rangen stands for a random positive variable generator ; nbparam for number of parameter of this distribution and param for a list of parameters
disP	the distribution of the success probability of Zi : p : disP is a 3 elements list : disfun stands for a distribution function ; nbparam for number of parameter of this distribution and param for a list of parameters
toplot	a logical variable to plot the variable Zi
calc	should the risk constants calculate?

Details

make simulation and estimation on the sample

Value

Describe the value returned If it is a LIST, use

CR	CR constant used in the exponential bound
R	the risk constant
T	the vector of durations between two declared side effects
lambdaEmp	estimate of lambda
muEmp	estimate of mu
