New Quantile Regression Model for Unit Interval Regressands
Engineering Reports, Volume 7, Issue 10, October 2025.The study developed a quantile regression model whose probability density function (PDF) is shown below. The reparameterized PDF plot for some selected parameter and quantile values depicts shapes such as approximately symmetric, increasing, decreasing, right‐skewed, and left‐skewed.

Deep learning the Hurst parameter of linear fractional processes and assessing its reliability
Quality and Reliability Engineering International, Volume 40, Issue 8, Page 4228-4246, December 2024.Abstract This research explores the reliability of deep learning, specifically Long Short‐Term Memory (LSTM) networks, for estimating the Hurst parameter in fractional stochastic processes. The study focuses on three types of processes: fractional Brownian motion (fBm), fractional Ornstein–Uhlenbeck (fOU) process, and linear fractional stable motions ...

Characteristic Function of Time-Inhomogeneous L\'evy-Driven Ornstein-Uhlenbeck Processes
, 2016 Distributional properties -including Laplace transforms- of integrals of Markov processes received a lot of attention in the literature. In this paper, we complete existing results in several ways.

, 2020 We study the parameter estimation problem of Vasicek Model driven by sub-fractional Brownian processes from discrete observations, and let {S_t^H,t>=0} denote a sub-fractional Brownian motion whose Hurst parameter 1 ...

Bonds versus Equities: Information for Investment
The Journal of Finance, Volume 79, Issue 6, Page 3893-3941, December 2024.ABSTRACT We provide a simple model of investment by a firm funded with debt and equity and empirical evidence to demonstrate that, once we control for the debt overhang problem with credit spreads, asset volatility is an unambiguously positive signal for investment, while equity volatility sends a mixed signal: Elevated volatility raises the option ...

Hydrocarbon‐derived thrombolites from the Outer Carpathians (Lower Cretaceous, Poland)
Sedimentology, Volume 71, Issue 7, Page 2183-2209, December 2024.Abstract Shallow marine thrombolites from a newly discovered Lower Cretaceous cold seep in the Outer Carpathians (Poland) were analysed in order to untangle the complex sedimentological and biogeochemical processes involved in their formation and their diagenetic modifications.

Firm‐level exposure to trade policy shocks: A multidimensional measurement approach
European Financial Management, Volume 30, Issue 4, Page 2135-2163, September 2024.Abstract We propose a firm‐level measure of exposure to trade policy shifts that combines characteristics (tradability of goods, share of output exported and corporate risk disclosures) with information from stock returns. We show that the measure reliably captures out‐of‐sample differences in price responses and sentiment related to trade tensions ...

US and Canadian term structures of interest rates: A forecasting comparison [PDF]
, 2016 This paper provides empirical evidence for the US and Canadian yield curves using a one- and two-factor Generalised Vasicek model, using a data set comprised of daily panel data over the period between 2003 and 2011, which includes the recent global ...

Numerical Methods for Partial Differential Equations, Volume 40, Issue 3, May 2024.Abstract We develop an efficient pricing approach for guaranteed minimum withdrawal benefits (GMWBs) with continuous withdrawals under a realistic modeling setting with jump‐diffusions and stochastic interest rate. Utilizing an impulse stochastic control framework, we formulate the no‐arbitrage GMWB pricing problem as a time‐dependent Hamilton‐Jacobi ...

International Journal of Finance &Economics, Volume 29, Issue 2, Page 1877-1895, April 2024.Abstract This paper defines a variety of game theoretic solution concepts in the language of soft set theory. We begin by defining the Nash equilibrium in pure strategies. We assume that the gains of the players are totally ordered and non‐desirable alternatives are absent. Moreover, we introduce the notions of strong and semi‐strong utility. These two
