It is the accompanying package to the book by Iacus (2008). where κ, θ and σ are constants. Solve the integral. Solving Stochastic Differential Equations (SDE) in R with diffeqr A heuristic (but very helpful) interpretation of the stochastic differential equation is that in a small time interval of length δ the stochastic process Xt changes its value by an amount that is normally distributed with expectation μ(Xt, t) δ and variance σ(Xt, t)² δ and is independent of the past behavior of the process. • Compare the solution for mean and covariance obtained fromthe numerical solutions of the ODE with the empirical value obtained from thesimulation. This results in an equation f(t,x) = σx + g(t), where the function g satisfies the ODE rg(t)+g0(t) = −rσx. Expectation and Variance of Stochastic Differential Equations.
