Here we develop methods for e±cient pricing multidimensional discrete-time American and Bermudan options by using regression based algorithms together with a new approach towards constructing upper bounds for the price of the option...

SEM researchers use Monte-Carlo simulations to ascertain the robustness of statisticalestimators and the performance of various fit indices under varying conditions of nonnormality.The efficacy of these Monte-Carlo simulations is closely related to thegeneration of non-normal data....

The purpose of this study is to investigate the effect of time- aggregation in discrete and continuous-time hazard models. A Monte Carlo study is conducted in which data are generated according to underlying continuous and discrete-time processes, which data are aggregated into daily, weekly and...
