CHEN MODEL

In finance, the 'Chen model' is a mathematical model describing the evolution of interest rates. It is a type of "one-factor model" (short rate model) as it describes interest rate movements as driven by only one source of market risk. It was the first stochastic mean and stochastic volatility model and it was introduced in 1996 by Lin Chen.
The dynamics of the instantaneous interest rate are specified by the stochastic differential equation:
