QuantLib: Short-rate modelling framework - kapl.org redirected
WebDetailed Description. This framework (corresponding to the ql/models/shortrate directory) implements some single-factor and two-factor short rate models. The models implemented in this library are widely used by practitioners. For the moment, the ShortRateModel class defines the short-rate dynamics with stochastic equations of the type. WebFor both of these reasons, models such as Black–Derman–Toy (lognormal and mean reverting) and Hull–White (mean reverting with lognormal variant available) are often preferred.: 385 The Kalotay–Williams–Fabozzi model is a lognormal analogue to the Ho–Lee model, although is less widely used than the latter two.

WebOther short rate models Two-factor Hull-White model In the two-factor Hull-White model, the instantaneous rate is represented as the sum of (i)the current rate r0 (t), and (ii)two stochastic state variables r1 (t) and r2 (t). In other words, r (t) = r0 (t) + r1 (t) + r2 (t). A natural interpretation of these variables is that r1 (t) controls ... WebIn the Hull-White model, there are two parameters related to the short rate process: mean reversion and volatility. Calibration is used to determine these parameters, such that the … WebKeywords One-Factor Hull-White model Two-Factor Hull-White model Calibration Swaption Coupon Bond Option 1 Introduction Interest rate stochastic models are widely used by practitioners for the evalu-ation of xed-income instruments.
