A BAYESIAN INFERENCE OF MULTIPLE STRUCTURAL BREAKS IN MEAN AND ERROR VARIANCE IN PANEL AR (1) MODEL

Varun Agiwal/ Jitendra Kumar/ Dahud Kehinde Shangodoyin

This paper explores the effect of multiple structural breaks to estimate the parameters and test the unit root hypothesis in panel data time series model under Bayesian perspective. These breaks are present in both mean and error variance at the same time point. We obtain Bayes estimates for different loss function using conditional posterior distribution, which is not coming in a closed form, and this is approximately explained by Gibbs sampling. For hypothesis testing, posterior odds ratio is (..)

IMPROVED ROTATION PATTERNS USING TWO AUXILIARY VARIABLES IN SUCCESSIVE SAMPLING

Jaishree Prabha Karna/ Dilip Chandra Nath

The present paper emphasizes the role of two auxiliary variables on both the occasions to improve the precision of estimates at the current (second) occasion in two-occasion successive sampling. Information on two auxiliary variables, which are positively correlated with the study variable, has been used with the aid of exponential type structures and an efficient estimation procedure of population mean on the current (second) occasion has been suggested. The behaviour of the proposed estimator (..)

JOINT RESPONSE PROPENSITY AND CALIBRATION METHOD

Seppo Laaksonen/ Auli Hämäläinen

This paper examines the chain of weights, beginning with the basic sampling weights for the respondents. These were then converted to reweights to reduce the bias due to missing quantities. If micro auxiliary variables are available for a gross sample, we suggest taking advantage first of the response propensity weights, and then of the calibrated weights with macro (aggregate) auxiliary variables. We also examined the calibration methodology that starts from the basic weights. Simulated data ba(..)

A NEW AND UNIFIED APPROACH IN GENERALIZING THE LINDLEY’S DISTRIBUTION WITH APPLICATIONS

Lahsen Bouchahed/ Halim Zeghdoudi

This paper proposes a new family of continuous distributions with one extra shape parameter called the generalized Zeghdoudi distributions (GZD). We investigate the shapes of the density and hazard rate function. We derive explicit expressions for some of its mathematical quantities. Various statistical properties like stochastic ordering, moment method, maximum likelihood estimation, entropies and limiting distribution of extreme order statistics are established. We prove the flexibility of the(..)

CANONICAL CORRELATION ANALYSIS IN THE CASE OF MULTIVARIATE REPEATED MEASURES DATA

Mirosław Krzyśko/ Wojciech Łukaszonek/ Waldemar Wołyński

In this paper, we present, in the real example, canonical variables applicable in the case of multivariate repeated measures data under the following assumptions: (1) multivariate normality for the vector of observations and (2) Kronecker product structure of the positive definite covariance matrix. These variables are especially useful when the number of observations is not large enough to estimate the covariance matrix, and thus the traditional canonical variables fail. Computational schemes f(..)

SEARCHING FOR CAUSES OF NECROTISING ENTEROCOLITIS. AN APPLICATION OF PROPENSITY MATCHING

Nicholas T. Longford

Necrotising enterocolitis (NEC) is a disease of the gastrointestinal tract afflicting preterm-born infants in the first few weeks of their lives. We estimate the effect of changing the feeding regimen of infants in their first 14 postnatal days by analysing the data from the UK National Neonatal Research Database. We avoid some problems with drawing causal inferences from observational data by reducing the analysis to the infants who spent the first 14 postnatal days (or longer) in neonatal care(..)

INDICATORS OF INTERNATIONAL TRADE ORIENTATION OF UKRAINE IN THE CONTEXT OF ASSESSMENT OF THE EFFECTIVENESS OF ITS EXPORT RELATIONS

N. Reznikova/ O. Osaulenko/ V. Panchenko

The approach to study the significance of trade relations between countries by analysing economic vulnerability, economic sensitivity, symmetry and asymmetry of the established economic links is proposed in the paper. This approach is adapted to an analysis of the trade dependence of Ukraine. The estimated interdependence ratios for Ukraine and its largest trade partners – the EU, the Russian Federation, post-Soviet countries, China, the USA and Brazil and India as emerging economies – are compa(..)

POWER ISHITA DISTRIBUTION AND ITS APPLICATION TO MODEL LIFETIME DATA

Kamlesh Kumar Shukla/ Rama Shanker

A study on two-parameter power Ishita distribution (PID), of which Ishita distribution introduced by Shanker and Shukla (2017 a) is a special case, has been carried out and its important statistical properties including shapes of the density, moments, skewness and kurtosis measures, hazard rate function, and stochastic ordering have been discussed. The maximum likelihood estimation has been discussed for estimating its parameters. An application of the distribution has been explained with a real(..)

SOME RESULTS FROM THE 2013 INTERNATIONAL YEAR OF STATISTICS

Jan Kordos

There are presented in this report, seven case studies of the uses of statistics in the past and present. I do not intend these examples to be exhaustive. I intend them primarily as educational examples for readers who would like to know: What is statistics good for? Also, to encourage the readers to study detailed reports from the 13 International Year of Statistics given in the notes of this report.

PRODUCT EXPONENTIAL METHOD OF IMPUTATION IN SAMPLE SURVEYS

Shakti Prasad

In this paper, a product exponential method of imputation has been suggested and their corresponding resultant point estimator has been proposed for estimating the population mean in sample surveys. The expression of bias and the mean square error of the suggested estimator has also been derived, up to the first order of large sample approximations. Compared with the mean imputation method, Singh and Deo (Statistical Papers (2003)) and Adapted estimator (Bahl and Tuteja (1991)), the simulation s(..)
