Ho-Lee model

In financial mathematics, the Ho-Lee model is a short rate model to predict future interest rates. It is the simplest model that can be calibrated to market data, by implying the form of $heta\_t$ from market prices.

Model

The short rate follows a normal process ::$dr\_t\; =\; heta\_t,\; dt\; +\; sigma,\; dW\_t$
