Nuclear Physics B, 2018 We present a systematic short time expansion for the generating function of the one point height probability distribution for the KPZ equation with droplet initial condition, which goes much beyond previous studies.

Landslides triggered by the 12 January 2010 Port-au-Prince, Haiti, Mw = 7.0 earthquake: visual interpretation, inventory compiling, and spatial distribution statistical analysis [PDF]
Natural Hazards and Earth System Sciences, 2014 The 12 January 2010 Port-au-Prince, Haiti, earthquake (Mw= 7.0) triggered tens of thousands of landslides. The purpose of this study is to investigate the correlations of the occurrence of landslides and the thicknesses of their erosion with topographic,

Estimating linear functionals in nonlinear regression with responses missing at random [PDF]
, 2009 We consider regression models with parametric (linear or nonlinear) regression function and allow responses to be ``missing at random.'' We assume that the errors have mean zero and are independent of the covariates.

Smooth tail index estimation [PDF]
, 2007 Both parametric distribution functions appearing in extreme value theory - the generalized extreme value distribution and the generalized Pareto distribution - have log-concave densities if the extreme value index gamma is in [-1,0].

Fourier methods for smooth distribution function estimation [PDF]
, 2013 In this paper we show how to use Fourier transform methods to analyze the asymptotic behavior of kernel distribution function estimators. Exact expressions for the mean integrated squared error in terms of the characteristic function of the distribution ...

Performance Evaluation of UWB Massive MIMO Channels With Favorable Propagation Features
IEEE Access, 2019 Radio wave propagation can be characterized by two major sets: empirical and deterministic models. Empirical models rely on the received signals' statistics and thus offer lower precision.

Composite Likelihood Inference by Nonparametric Saddlepoint Tests [PDF]
, 2013 The class of composite likelihood functions provides a flexible and powerful toolkit to carry out approximate inference for complex statistical models when the full likelihood is either impossible to specify or unfeasible to compute.

Size and power properties of some tests in the Birnbaum-Saunders regression model
, 2010 The Birnbaum-Saunders distribution has been used quite effectively to model times to failure for materials subject to fatigue and for modeling lifetime data.
