Following Cox & Wermuth (1994, 2002), we show that the distribution of a set of binary observable variables, induced by a certain discrete latent variable model, may be approximated by a quadratic ...
Jim Gatheral proposes efficient and easy-to-implement Riemann sum and hybrid quadratic exponential schemes for the simulation of rough affine forward variance models The class of affine forward ...
Parameterizations for natural exponential families (NEF's) with quadratic variance functions (QVF's) are compared according to the nearness to normality of the likelihood and posterior distribution.
