MLMC methods for approximating expectations of the Heston 3/2-model with positivity-preserving properties.
Statistieken
"The computational cost of approximating the quantity (1.2) would be O(ϵ−3), where ϵ > 0 is the required target accuracy measured by the root-mean-square error."
"The key idea of the MLMC to reduce the overall computational complexity lies in the fact that more paths are simulated on the coarser level and fewer paths are simulated on the finer level."
Citaten
"The proposed scheme can be explicitly solved and is positivity-preserving unconditionally, i.e., for any time step-size h > 0."
