In this paper we investigate the properties of the estimator of degree of differencing the fractional d in long memory time series analysis via consistent spectral density estimation. It is shown t...
Intensive computational methods have been used by Earth scientists in a wide range of problems in data inversion and uncertainty quantication such as earthquake epicenter location and climate projec...
Our main focus is on the basic reproduction number, a quantity of central importance in mathematical epidemic theory, whose value essentially dictates whether or not a large epidemic outbreak can oc...
Hidden Markov models (HMMs) and related models have become stan- dard in statistics during the last 15C2 years, with applications in diverse areas like speech and other statistical signal processing...
The limiting behavior of M-estimates for a Iinear model when the regressors and/or errors have heavy tailed distributions is given. By hermy toil we mean that the distribution is in the domain of a...
It would appear useful to come back to the question of admissibility in imear estimation on a general Gauss-Markov model. We prove how a functional approach to this problem, based on a very importa...
Empirical distributions in nance and economics might show heavy tails, volatility clustering, varying mean returns and multimodality as part of their features. However, most statistical models avail...
Our primary goal is to obtain a smoothed summary estimate of the magnetic eld generated in and near to the Milky Way by using Faraday rotation measures (RMs) Each RM in our data set provides an inte...
We describe a method for quantifying the lack of t in a proposed family of distributions. The method involves estimating the posterior distribu- tion of the Kullback-Leibler information between the ...
In the paper we consider the problem of estimating stochastic intensity of a point process from multiplicative intensity model using the method of sieves of Grenander [6]. Basic properties of the h...
In this paper we obtain convergence rates for sieved maximum-likelihood &timators of the log-hazard function in a censoring model. We also establish convergence results for an adaptive version of t...
This paper describe6 the adaptive estimation problem based on ranks for the parameter of an ARMA process. Tbe local asymptotic normality property with a ranked based central sequence allows for the...
The use of variable kernel mass in density estimation
We analyze the asymptotic behaviour of the tapered discrete Fourier transforms far random fields with singular spectrum. The results are used to establish consistency and asymptotic normality for s...
The process of calibrating radiocarbon determinations onto the cal- endar scale involves, as a rst stage, the estimation of the relationship between calendar and radiocarbon ages (the radiocarbon ca...
