In this paper, we consider the following natural problem:
suppose pi and pa are two probability measures with fimte
supports S(pl), S(p2), respectively, such that IS(,u1)1 = lSbz)l and
S(pl)uS(pZ) ...

Princing European options on instruments with a constant dividend yield:The randomized discrete-time approach
Option pricing dividends randomization alternative models
2009/9/21
Due to the well-known fact that market returns are not
normally distributed, we use generalized hyperbolic distributions for
pricing options in a randomized discrete-time setup. The obtained
formul...
PROBABILITY OF FAILURE WITH DISCRETE CLAIM DISTRIBUTION
Failure probability ruin probability finite time
2009/9/18
A concept 01 the probability of failure is introduced.
Some popular methods of exact computation of ruin probability are
adopted to compute failure probability. Based on the f o d a presented
in [5...

Exponential families normal cone maximum likelihood estimates exponential random graphs
2009/9/16
There has been an explosion of interest in statistical models for analyzing network data, and considerable interest in the class of exponential random graph (ERG) models, especially in connection with...

2009/3/23
The nonlinear filter associated with the discrete time signal-observation model $(X_k,Y_k)$ is known to forget its initial condition as $ktoinfty$ regardless of the observation structure when the sign...
