The statistical inference of the Vasicek model driven by small Lévy process has a long history. In this paper, we consider the problem of parameter estimation for Vasicek model dXt = (μ-θXt)dt + εdLdt, t ∈ [0,1], X0 = x0, driven by small fractional Levy noise with the known parameter d less than one half, based on discrete high-frequency observations at regularly spaced time points

2.1. Vasicek Short Rate Model. The Vasicek model was proposed in Vasicek [1977], whereby the short rate is described by the SDE (2.1) dr t= ( r r t)dt+ ˙dZ t for positive constants rand ˙and . The parameter denotes the speed of reversion of the short rate r t to the mean reverting level r. The parameter rdenotes the average short rate.

They belong to the set of equilibrium models. These models generate predicted term structures whose shape depends on the models parameters and the initial short rate. Chapter 4 is focused on our goals.

Examples of short-rate models include Cox (1975), Vasicek (1977), Dothan (1978), Brennan and Schwartz (1980), Marsh and Rosenfeld (1983), and Cox, Ingersoll, and Ross (1985), to name but a few. While continuous-time models are popular in theoretical work, empirical estimation of model parameters presents a number of challenges. First, estimation

These models generate predicted term structures whose shape depends on the models parameters and the initial short rate. Chapter 4 is focused on our goals. The paper is organized as follows: In section 2, we introduce model (1.1) under the Vasicek ASRF model framework, review the parameter estimation methodologies proposed in [27] for the multifactor Vasicek model (2.3), and show formulations (1.2) - (1.4). Analytical formulas for conditional PDs for stress testing are also shown in this section.

Parameter Estimation Since Vasicek first introduced his model of short term risk free interest rate the discussion of the parameters estimation continues. In this section we will discuss the well-known techniques for parameter estimation 3.1 Least Square Regressions 3.1.1 Data Let the time step Δt = 0.25, the mean reversion rate = 3.0, long term mean =1.0, and the volatility =0.50.

The path simulation is based on the the Euler Maruyana Scheme for Vasicek model which follows 2.1. Vasicek Short Rate Model.
