Group sequential design for randomized trials using “first hitting time” model

Statistics in Medicine, 2022
AbstractGroup sequential design (GSD) has become a popular choice in recent clinical trials as it improves trial efficiency by providing options for early termination. The implementation of traditional tests for survival analysis (eg, the log‐rank test and the Cox proportional hazard (PH) model) in the GSD setting has been widely discussed.

Uncertain optimal control problem with the first hitting time objective and application to a portfolio selection model

Journal of Intelligent & Fuzzy Systems, 2022
 This paper discusses an uncertain time optimal control problem by considering time efficiency, which is to optimize the objective function about the first hitting time subject to uncertain differential equations. According to the definition of the α-path, the uncertain time optimal control problem is transformed into an equivalent deterministic ...

RELIABILITY INDEX AND OPTION PRICING FORMULAS OF THE FIRST-HITTING TIME MODEL BASED ON THE UNCERTAIN FRACTIONAL-ORDER DIFFERENTIAL EQUATION WITH CAPUTO TYPE

Fractals, 2020
Since the ability to control the investor’s income or loss within a certain range, barrier option has been among the most popular path-dependent options where its payoff depends on whether or not the underlying asset’s price reaches a given “barrier”. First, assuming the underlying asset as an uncertain variable for the case that the Caputo fractional-

First Hitting Time Models for Lifetime Data

, 2003
Publisher Summary The idea of a first hitting time is quite broad. For example, in industrial quality control, the run time until a quality measure first reaches an out-of-control limit is a first hitting time and a standard quantity considered in quality management.

Issues in Fitting Inverse Gaussian First Hitting Time Regression Models for Lifetime Data

Communications in Statistics - Simulation and Computation, 2013
Inverse Gaussian first hitting time regression models sometimes provide an attractive representation of lifetime data. Various authors comment that dependence of both parameters on the same covariate may imply multicollinearity. The frequent appearance of conflicting signs for the two coefficients of the same covariate may be related to this.
