Applicability of the Multi- Group Confirmatory Factor Analysis to Construction of Business Sentiment Indicators
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)The paper presents arguments that advocate for application of the multi-group confirmatory factor analysis as a tool for constructing sentiment indicators in business surveys. Reliable measurement and comparisons of the ... -
Bayesian Exponential Survival Model in the Analysis of Unemployment Duration Determinants
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)The primary objective of the work is to identify demographic and socio-economic factors influencing the unemployment duration in the recent period in Poland. Different approaches to the problem have been applied. In this ... -
Comparison of Stability of Classical Taxonomy Bagging Metod with Bagging Based on Co-Occurence Data
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)Ensemble approach has been successfully applied in the context of supervised learning to increase the accuracy and stability of classification. Recently, analogous techniques for cluster analysis have been suggested in ... -
Evaluation of College Students with Application of Latent Class Analysis
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)In social sciences, especially in economy, to reveal relations between variables it’s easy to apply many known statistical tools when we deal with observable (measureable) variables. The problems appear when dealing with ... -
Hierarchical Log-linear Models for Contingency Tables
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)Log-linear models are widely used for qualitative data in multidimensional contingency tables. Hierarchical log-linear models are models that include all lower-order terms composed from variables contained in a higher-order ... -
Imputation of Missing Data Using R Package
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)Missing data are quite common in practical applications of statistical methods. Imputation is general statistical method for the analysis of incomplete data sets. The goal of the paper is to review selected imputation ... -

Notes on the Optimum Chemical Balance Weighing Design
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)In the paper, the model of the chemical balance weighing design, i.e. model in that the result of experiment we can describe as linear function of unknown measurements of objects with known factors, is presented. ... -
On Generating Correlated Pseudo-Random Binary Numbers
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)The paper is devoted to the problem of generating sequences of binary vectors having joint distribution allowing for correlation between individual elements. A procedure for generating such a distribution from uncorrelated ... -
On Pseudo-EBLUP Under Some Model for Longitudinal Data with Auxiliary Variables
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)The problem of modeling longitudinal profiles is considered assuming that the population and elements affiliation to subpopulations may change in time. The considerations are based on a model with auxiliary variables for ... -
On Testing the Significance of the Coefficients in the Multiple Regression Analysis
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)The multiple regression analysis is a statistical tool for the investigation relationships between the dependent and independent variables. There are some procedures for selecting a subset of given predictors. These ... -

Some Construction of Regular A-Optimal Spring Balance Weighing Designs for Even Number of Objects
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)In the paper, the problem of construction of the spring balance weighing designs satisfying the criterion of A-optimality is discussed. The incidence matrices of the partially incomplete block designs are used for ... -
Some Properties of the Robust Trend Tests
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)Formal testing of whether a time series contains a trend is greatly complicated by the fact that in practice it is not known whether the trend is embedded in an I(0) or I(1), series, that is, within a weakly or strongly ... -
Special Cases of Some General Formula for Price Indices
Białek, Jacek
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)
In the paper we present a general formula for aggregative price indices that satisfies most postulates coming from the axiomatic price index theory. We show that a lot of known and useful price indices are particular ... -
Statistical Inference from Complex Sample with SAS on the Example of Household Budget Surveys
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)Many sample surveys are not based on simple or unrestricted random samples, but usually on complex samples with stratification, clustering, unequal inclusion probabilities and multistage sampling. To estimate a parameter, ...
