Recent Submissions

  • Likert Scale and Change in Range of Response Categories vs. the Factors Extraction in EFA Model 

    Tarka, Piotr (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    The objective of the article is the comparative analysis of Likert rating scale based on the following range of response categories, i.e. 5, 7, 9 and 11 in context of the appropriate process of factors extraction in ...
  • Better Alternatives for Stepwise Discriminant Analysis 

    Stąpor, Katarzyna (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    Discriminant Analysis can be best defined as a technique which allows the classification of an individual into several distinctive populations on the basis of a set of measurements. Stepwise discriminant analysis (SDA) is ...
  • Introduction 

    Domański, Czesław; Zalewska, Elżbieta (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
  • Feature Selection and the Chessboard Problem 

    Kubus, Mariusz (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    Feature selection methods are usually classified into three groups: filters, wrappers and embedded methods. The second important criterion of their classification is an individual or multivariate approach to evaluation of ...
  • On the Method of Detecting Changes in Trend Using Permutation Tests 

    Miłek, Michał; Kończak, Grzegorz (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    The article presents a proposal of the test for detecting changes in trend. The proposed procedure refers to the permutation test. The use of this procedure allowed the adoption of fairly general assumptions. The proposed ...
  • Empirical and Kernel Estimation of the ROC Curve 

    Baszczyńska, Aleksandra (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    The paper presents chosen methods for estimating the ROC (Receiver Operating Characteristic) curve, including parametric and nonparametric procedures. Nonparametric approach may involve the use of empirical method or kernel ...
  • Comparative Analysis of Sigma-Based, Quantile-Based and Time Series VaR Estimators 

    Małecka, Marta (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    Since its inception at the end of the XX century, VaR risk measure has gained massive popularity. It is synthetic, easy in interpretation and offers comparability of risk levels reported by different institutions. However, ...
  • On D-optimal Chemical Balance Weighing Designs 

    Ceranka, Bronisław; Graczyk, Małgorzata (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    The paper deals with the problem of determining the chemical balance weighing designs satisfying the criterion of D-optimality under assumption that the measurement errors are equally correlated and they have the same ...
  • Application of Survival Analysis in Efficiency Evaluation of Professional Effectiveness Enhancement Programme 

    Bieszk-Stolorz, Beata; Markowicz, Iwona (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    The purpose of the paper is to evaluate the effect of a professional effectiveness enhancing programme on unemployment spells. The analysed programme was implemented by the Poviat Labour Office in Szczecin in 2009 and 2010 ...
