In a variety of research domains, data are generated as a consequence of the count process and may possess an ‘excess’ of zeros. There have been many attempts to analyse such data using different statistical methods, including the zero-inflated Poisson (ZiP) and zero-inflated binomial (ZiB) models. The interpretation of these models is however problematic if the covariates considered for the no...

Stochastic differential equations and the Black-Scholes PDE. We derived the BlackScholes formula by using arbitrage (risk-neutral) valuation in a discrete-time, binomial tree setting, then passing to a continuum limit. This section explores an alternative, continuoustime approach via the Ito calculus and the Black-Scholes differential equation. This material is very standard; I like Wilmott-How...

We revisit the American put and call option valuation problems. We derive analytical formulas for the option prices and approximate ordinary differential equations for the optimal exercise boundaries. Numerical simulations yield accurate option prices and comparable computational speeds when benchmarked against the binomial method for calculating option prices. Our approach is based on the Mell...

In this paper we consider partnership deals under uncertainty but with downstream flexibility. We confine ourselves to bilateral deals and focus on the effect of options on the synergy set, the ‘core’, of a partnership deal. We distinguish between cooperative options, which are exercised jointly and in the interest of maximizing the total deal value, and non-cooperative options, which are exerc...

BACKGROUND AND OBJECTIVE The treatment of hepatocellular carcinoma (HCC) involves multidisciplinary clinical divisions and patients may be admitted to clinical divisions of different disciplinary nature. Few studies have assessed the potential effect of hospital admissions into different divisions on patient treatment options and survival. This study aimed to analyze this potential effect. ME...

Binomial trees have been used extensively for broadcasting in clusters of workstations. In the case of heterogeneous nondedicated clusters and grid environments, the broadcasting occurs over a heterogeneous network, and the performance obtained by the broadcast algorithm will depend on the organization of the nodes onto the binomial tree. The organization of the nodes should take into account t...

In this expository paper we illustrate the generality of game theoretic probability protocols of Shafer and Vovk (2001) in finite-horizon discrete games. By restricting ourselves to finite-horizon discrete games, we can explicitly describe how discrete distributions with finite support and the discrete pricing formulas, such as the Cox-Ross-Rubinstein formula, are naturally derived from game-th...

We propose an improved binomial lattice approach for valuing complex option problems whose payoff depends on multiple state variables following correlated geometric Brownian processes. The proposed approach relies on two main ideas: a specific change of time scale as in the log-trasformed binomial approach by Trigeorgis (1991), and a change of basis of the asset span, to trasform them into unco...

In the context of an asset paying affine-type discrete dividends, we present closed analytical approximations for the pricing of European vanilla options in the Black-Scholes model with time-dependent parameters. They are obtained using a stochastic Taylor expansion around a shifted lognormal proxy model. The final formulae are respectively first, second and third order approximations w.r.t. th...

Based on the theory of real options, this paper establishes a investment decision-making model that could evaluate the development of CCS considering some uncertainties: feed-in tariff, the clean price, carbon price, incentives and subsidies from the government and the progress of technology. This model calculates the investment value of CCS project by studying the binomial tree model of real o...
