In emhawkes: Exponential Multivariate Hawkes Model

Description

Simulate a multivariate Hawkes process. Generic function hsim.

The method simulate multivariate Hawkes processes. The object hspec-class contains the parameter values such as mu, alpha, beta. The mark (jump) structure may or may not be included. It returns an object of class hreal which contains inter_arrival, arrival, type, mark, N, Nc, lambda, lambda_component, rambda, rambda_component.

Usage

hsim(object, size = 100, lambda0 = NULL, N0 = NULL)

## S4 method for signature 'hspec'
hsim(object, size = 100, lambda0 = NULL, N0 = NULL)

Arguments

object	hspec-class. This object includes the parameter values.
size	the number of observations.
lambda0	the starting values of lambda component. numeric or matrix.
N0	the starting values of N

Value

hreal S3-object, summary of the realization of the Haweks model

Examples

mu <- c(0.1, 0.1)
alpha <- matrix(c(0.2, 0.1, 0.1, 0.2), nrow=2, byrow=TRUE)
beta <- matrix(c(0.9, 0.9, 0.9, 0.9), nrow=2, byrow=TRUE)
h <- new("hspec", mu=mu, alpha=alpha, beta=beta)
res <- hsim(h, size=100)
