Pricing basket options with the first three moments of the basket: log-normal models and beyond

no code implementations16 Feb 2023 Dongdong Hu, Hasanjan Sayit, Frederi Viens

Options on baskets (linear combinations) of assets are notoriously challenging to price using even the simplest log-normal continuous-time stochastic models for the individual assets.

Market Making under a Weakly Consistent Limit Order Book Model

no code implementations18 Mar 2019 Baron Law, Frederi Viens

We develop a new market-making model, from the ground up, which is tailored towards high-frequency trading under a limit order book (LOB), based on the well-known classification of order types in market microstructure.

Neutron drip line in the Ca region from Bayesian model averaging

no code implementations22 Jan 2019 Léo Neufcourt, Yuchen Cao, Witold Nazarewicz, Erik Olsen, Frederi Viens

In particular, considering the current experimental information and current global mass models, we predict that $^{68}$Ca has an average posterior probability ${p_{ex}\approx76}$% to be bound to two-neutron emission while the nucleus $^{61}$Ca is likely to decay by emitting a neutron (${p_{ex}\approx 46}$ %).

Bayesian approach to model-based extrapolation of nuclear observables

no code implementations1 Jun 2018 Léo Neufcourt, Yuchen Cao, Witold Nazarewicz, Frederi Viens

The increase in the predictive power is quite astonishing: the resulting rms deviations from experiment on the testing dataset are similar to those of more phenomenological models.
