In shill1729/FeynmanKacSolver: Feynman-Kac PDE solver for Ito diffusions and processes

Description

Non exported Wrapper to sample_path_em to directly simulate a sample path of Brownian motion without having to specify the trivial coefficient functions. This function should not be called directly but rather through sample_path with continuous.model set to "bm".

Usage

sample_path_bm(t, IC = NULL, parameters = NULL, jumps = NULL, n = 10000)

Arguments

t	length of time to simulate over
IC	list of initial conditions
parameters	list of parameters, in this case for the jump-dynamics
jumps	a list of objects defining the jump-size distribution, can be NULL for purely continuous models
n	number of time sub-intervals in the discretization

Details

The list jumps should contain

• distr the name of the distribution of the jump-sizes e.g. "norm", "unif", "kou"

• param named list of parameters for the distribution matching the input in rdistr for a given "distr".

Value

data.frame containing t (time) and X (state).
