Mod-Poisson approximation schemes: Applications to credit risk

Pierre-Loïc Méliot, Ashkan Nikeghbali, Gabriele Visentin

We introduce a new numerical approximation method for functionals of factor credit portfolio models based on the theory of mod- convergence and mod- approximation schemes. Th…

Mod-Poisson approximation schemes and higher-order Chen-Stein inequalities

Pierre-Loïc Méliot, Ashkan Nikeghbali, Gabriele Visentin

In this article, we provide an extension of the Chen-Stein inequality for Poisson approximation in the total variation distance for sums of independent Bernoulli random variables i…

Asymptotics of the major index of a random standard tableau

Pierre-Loïc Méliot, Ashkan Nikeghbali

In this article, we establish the mod- convergence of the major index of a uniform random standard tableau whose shape converges in the Thoma simplex. This implies various proba…

Gaussian approximations for random vectors

Pierre-Loïc Méliot, Ashkan Nikeghbali

We present several refinements on the fluctuations of sequences of random vectors (with values in the Euclidean space ) which converge after normalization to a multid…

On the precise deviations of the characteristic polynomial of a random matrix

Pierre-Loïc Méliot, Ashkan Nikeghbali

In this paper, using techniques developed in our earlier works on the theory of mod-Gaussian convergence, we prove precise moderate and large deviation results for the logarithm of…

A central limit theorem for singular graphons

Pierre-Loïc Méliot

We associate to a graphon the sequence of -random graphs . We say that the graphon is singular if, for any finite graph , the homomorphism density $t…
