simultaneous equations
... B matrices, since the zero components are not to be estimated. Spell out the definitional relation Π Γ = B in greater detail we have two blocks of equations where the coefficients of the first structural equation are now denoted by subscript 1. Now Γ is MM matrix but the first equation is M1 vect ...

Itô diffusion
In mathematics — specifically, in stochastic analysis — an Itô diffusion is a solution to a specific type of stochastic differential equation. That equation is similar to the Langevin equation used in physics to describe the Brownian motion of a particle subjected to a potential in a viscous fluid. Itô diffusions are named after the Japanese mathematician Kiyosi Itô.
