Modeling the probabilistic distribution of the impact factor

Sarabia, José María; Prieto, Faustino; Trueba, Carmen - In: Journal of Informetrics 6 (2012) 1, pp. 66-79

probabilistic quantile function corresponding to the Mansilla's two-exponent law is obtained. This result is particularly relevant …

Quantile based entropy function

Sunoj, S.M.; Sankaran, P.G. - In: Statistics & Probability Letters 82 (2012) 6, pp. 1049-1053

Quantile functions are efficient and equivalent alternatives to distribution functions in modeling and analysis of statistical data (see Gilchrist, 2000; Nair and Sankaran, 2009). Motivated by this, in the present paper, we introduce a quantile based Shannon entropy function. We also introduce...

Uniform Bias Study and Bahadur Representation for Local Polynomial Estimators of the Conditional Quantile Function

Guerre, Emmanuel; Sabbah, Camille - School of Economics and Finance, Queen Mary - 2009

quantile function and its derivatives. The bias and Bahadur remainder term are studied uniformly with respect to the quantile … differentiability order of the conditional quantile function. Applications of the results deal with global optimal consistency rates of … density function. The latter allows to obtain a simple estimator of the conditional quantile function of the private values in …

Quantile-Function Based Null Distribution in Resampling Based Multiple Testing

Laan, Mark van der; Hubbard, Alan - In: Statistical Applications in Genetics and Molecular Biology 5 (2009) 1, pp. 14-14

Simultaneously testing a collection of null hypotheses about a data generating distribution based on a sample of independent and identically distributed observations is a fundamental and important statistical problem involving many applications. Methods based on marginal null distributions...

Autoregression with Non-Gaussian Innovations

Cai, Yuzhi - In: Journal of Time Series Econometrics 1 (2009) 2

Many economics and finance time series are non-Gaussian. In this paper, we propose a Bayesian approach to non-Gaussian autoregressive time series models via quantile functions. This approach is parametric, so we also compare the proposed parametric approach with a semi-parametric approach....

Estimation of Treatment Effects in Randomized Trials with Noncompliance and a Dichotomous Outcome

Laan, Mark van der; Hubbard, Alan; Jewell, Nicholas - Berkeley Electronic Press - 2004

We propose a class of estimators of a received treatment effect on a dichotomous outcome among the treated subjects within covariate and treatment arm strata in randomized trials with non-compliance. Recent articles by Vansteelandt and Goethebeur (2003), and Robins and Rotnitzky (2004) have...

Quasi-medians are robust and relatively efficient estimators of a common mean given multivariate normality

Hutson, Alan D. - In: Statistics & Probability Letters 57 (2002) 4, pp. 403-408

In this note we examine the efficiency of averaging marginal quasi-medians as compared to averaging marginal sample means when estimating a common location parameter given multivariate normal data. It is shown that the efficiency of certain quasi-medians approach that of the sample mean as the...
