Lie Symmetry Analysis for the Fractal Bond‐Pricing Model of Mathematical Finance
The classical bond‐pricing models, as important financial tools, show strong vitality in bond pricing. However, these models also expose their theoretical defects, which leads to inconsistencies with the actual observation results and usually causes the theoretical prices of bonds to be lower than the actual market prices in the financial market.

Properties, Bounds, and Estimation of Rényi Entropy in Consecutive k‐out‐of‐n:G Systems
This study investigates the Renyi entropy properties of consecutive k‐out‐of‐n : G systems. Initially, a formula for the Renyi entropy of the lifetime of a consecutive k‐out‐of‐n:G system is derived, offering a thorough insight into its Renyi entropy characteristics.

The Fractional Ornstein-Uhlenbeck Process: Term Structure Theory and Application [PDF]
The paper revisits dynamic term structure models (DTSMs) and proposes a new way in dealing with the limitation of the classical affine models. In particular, this paper expands the flexibility of the DTSMs by applying a fractional Brownian motion as the ...

Specification analysis in regime-switching continuous-time diffusion models for market volatility [PDF]
We examine model specification in regime-switching continuous-time diffusions for modeling S&P 500 Volatility Index (VIX). Our investigation is carried out under two nonlinear diffusion frameworks, the NLDCEV and the CIRCEV frameworks, and our focus is ...

Comments on “A Selective Overview of Nonparametric Methods in Financial Econometrics” by Jianqing Fan [PDF]
Our comments on Fan’s paper will concentrate on two issues that relate in important ways to the paper’s focus on misspecification and discretization bias and the role of nonparametric methods in empirical finance.

LEAST SQUARES ESTIMATORS OF DRIFT PARAMETER FOR DISCRETELY OBSERVED FRACTIONAL VASICEK-TYPE MODEL
We study the drift parameter estimation problem for a fractional Vasicek-typemodel X:={X_t,t⩾0}, that is defined as dX_t=θ(µ+X_t)dt+dB_t^H, t⩾0 withunknown parameters θ>0 and µ∈â„ÂÂ, where {B_t^H,t⩾0}is a fractional Brownianmotion of Hurst index H ∈]0, 1 ...
