Space-Time Modeling of Rainfall Rate for Satellite Networks
IEEE Access, 2020 A new comprehensive space-time model for the characterization of point rainfall rate is presented. A detailed assessment of four key rain characteristics (probability of rain/no rain condition, first and second order lognormal statistics and, space and ...

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].

Asymptotic goodness-of-fit tests for point processes based on scaled empirical K-functions [PDF]
, 2017 We study sequences of scaled edge-corrected empirical (generalized) K-functions (modifying Ripley's K-function) each of them constructed from a single observation of a d-dimensional fourth-order stationary point process in a sampling window which grows ...

Bayesian model selection for exponential random graph models via adjusted pseudolikelihoods [PDF]
, 2017 Models with intractable likelihood functions arise in areas including network analysis and spatial statistics, especially those involving Gibbs random fields.

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.

A subsampled double bootstrap for massive data [PDF]
, 2015 The bootstrap is a popular and powerful method for assessing precision of estimators and inferential methods. However, for massive datasets which are increasingly prevalent, the bootstrap becomes prohibitively costly in computation and its feasibility is

Local power of the LR, Wald, score and gradient tests in dispersion models
, 2011 We derive asymptotic expansions up to order $n^{-1/2}$ for the nonnull distribution functions of the likelihood ratio, Wald, score and gradient test statistics in the class of dispersion models, under a sequence of Pitman alternatives.

Delta method in large deviations and moderate deviations for estimators [PDF]
, 2011 The delta method is a popular and elementary tool for deriving limiting distributions of transformed statistics, while applications of asymptotic distributions do not allow one to obtain desirable accuracy of approximation for tail probabilities.

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.
