The process Y defined before as =, is itself a stochastic process with time parameter t, which is also sometimes written as Y = H · X (Rogers & Williams 2000).Alternatively, the integral is often written in differential form dY = H dX, which is equivalent to Y − Y 0 = H · X.As Itô calculus is concerned with continuous-time …

This method was later extended to more general square integrable martingales and, then, to the class of semimartingales.
WebbThe calculation of the variance involves a simple application of the Ito isometry. In particular, if f (s, t) is deterministic, then 2 t t E ... Because PtT is positive, the forward short rate process ftT is an Ito process iff −∂T PtT is an Ito process.
