28 p, 938.7 KB Estimation of finite population distribution function with auxiliary information in a complex survey sampling / Abbas, Mohsin (Quaid-i-Azam University (Pakistan)) ; Haq, Abdul (Quaid-i-Azam University (Pakistan))
In this paper, we consider the problem of estimating the finite population cumulative distribution function (CDF) in a complex survey sampling, which includes two-stage and three-stage cluster sampling schemes with and without stratification. [...]

22 p, 1.1 MB Modified almost unbiased two-parameter estimator for the Poisson regression model with an application to accident data / Alheety, Mustafa I. (University of Anbar (Irak). Department of Mathematics,College of Education for Pure Sciences) ; Qasim, Muhammad (Jönköping University (Suècia). Department of Economics, Finance and Statistics) ; Månsson, Kristofer (Jönköping University (Suècia). Department of Economics, Finance and Statistics) ; Kibria, B. M. Golam (Florida International University. Department of Mathematics and Statistics)
Due to the large amount of accidents negatively affecting the wellbeing of the survivors and their families, a substantial amount of research is conducted to determine the causes of road accidents. This type of data come in the form of non-negative integers and may be modelled using the Poisson regression model. [...]

36 p, 514.8 KB Small area estimation of additive parameters under unit-level generalized linear mixed models / Hobza, Tomáš (Czech Technical University in Prague. Department of Mathematics) ; Marhuenda García, Yolanda (Universidad Miguel Hernández. Instituto Centro de Investigación Operativa) ; Morales González, Domingo (Universidad Miguel Hernández. Instituto Centro de Investigación Operativa)
Average incomes and poverty proportions are additive parameters obtained as averages of a given function of an income variable. As the variable income has an asymmetric distribution, it is not properly modelled via normal distributions. [...]

22 p, 387.0 KB Sampling design variance estimation of small area estimators in the Spanish Labour Force Survey / Herrador Cansado, Montserrat ; Morales González, Domingo ; Esteban Álvarez, María Dolores ; Sánchez, Ángel ; Santamaría Arana, Laureano ; Marhuenda García, Yolanda ; Pérez Mas, Antonio
The main goal of this paper is to investigate how to estimate sampling design variances of modelbased and model-assisted small area estimators in a complex survey sampling setup. For this purpose the Spanish Labour Force Survey is considered. [...]

24 p, 139.4 KB On ratio and product methods with certain known population parameters of auxiliary variable in sample surveys / Singh, Housila P. ; Tailor, Ritesh ; Tailor, Rajesh
This paper proposes two ratio and product-type estimators using transformation based on known minimum and maximum values of auxiliary variable. The biases and mean squared errors of the suggested estimators are obtained under large sample approximation. [...]

18 p, 324.1 KB Small-sample inference about variance and its transformations / Longford, Nicholas T. ; SNTL Statistics Research and Consulting
We discuss minimum mean squared error and Bayesian estimation of the variance and its common transformations in the setting of normality and homoscedasticity with small samples, for which asymptotics do not apply. [...]

14 p, 181.4 KB A general procedure of estimating the population mean in the presence of non-response under double sampling using auxiliary information / Singh, Housila P. ; Kumar, Sunil
In the present study, we propose a general class of estimators for population mean of the study variable in the presence of non-response using auxiliary information under double sampling. The expression of mean squared error (MSE) of the proposed class of estimators is derived under double (two-stage) sampling. [...]

16 p, 135.0 KB An alternative analysis of variance / Longford, Nicholas T. (SNTL, Reading, United Kingdom) ; Universitat Pompeu Fabra
The one-way analysis of variance is a staple of elementary statistics courses. The hypothesis test of homogeneity of the means encourages the use of the selected-model based estimators which are usually assessed without any regard for the uncertainty about the outcome of the test. [...]

22 p, 220.2 KB Improving small area estimation by combining surveys : new perspectives in regional statistics / Costa, Àlex (Institut d'Estadística de Catalunya) ; Satorra, Albert (Universitat Pompeu Fabra) ; Ventura, Eva (Universitat Pompeu Fabra)
A national survey designed for estimating a specific population quantity is sometimes used for estimation of this quantity also for a small area, such as a province. Budget constraints do not allow a greater sample size for the small area, and so other means of improving estimation have to be devised. [...]
