We can now state, without proof, a multivariate version of Itô’s lemma. In the documentation for the ItoProcess it says: Converting an ItoProcess to standard form automatically makes use of Ito's lemma.

Kiyoshi Ito is a mathematician from Hokusei, An Ito process can be thought of as a stochastic differential equation. Ito's lemma provides the rules for computing the Ito process of a function of Ito processes.

APPENDIX 13A: GENERALIZATION OF ITO'S LEMMA Ito's lemma as presented in Appendix 10A provides the process followed by a function of a single stochastic variable. Here we present a generalized version of Ito's lemma for the process followed by a function of several stochastic variables. Suppose that a function,/, depends on the n variables x\,X2

Finally, the result of (5) repeats what we know regarding the square of an inﬁnitesimal quantity. The Lemma Now consider a diﬀerentiable function of a stochastic variable x that is driven by a Wiener process described by the equation 2015-03-20 First, I defined Ito's lemma--that means differentiation in Ito calculus. Then I defined integration using differentiation-- integration was an inverse operation of the differentiation. But this integration also had an alternative description in terms of Riemannian sums, where you're taking just the leftmost point as the reference point for each interval.
