NOTES ON THE ESTIMATORS PROPERTIES IN CASE OF IMPUTED DATA SETS (Uwagi na temat wlasnosci estymatorow wyznaczanych na bazie niepelnych danych)

Beata Zmyslona

Ekonometria > 2011 > 30 (Zastosowania metod ilościowych) > 83-93

In current surveys practice the most common method for handling non-response item is simple imputation. The simple imputation methods are the prediction methods for missing data. The imputed values are treated as if they were observed. This results in under or overestimation of the estimator variance, especially if the missing data mechanism is non-random. Simple imputation is inappropriate when the...

Aneta Rybicka

Ekonometria > 2011 > 30 (Zastosowania metod ilościowych) > 36-46

A very common issue which appears while choosing a research method is the problem of different scales of measurements. This problem appears when considering a large number of variables and many levels of variables. Another very important problem of choosing the appropriate method of measurement is to create a situation that most closely reflects the actual decision-making process by the respondents...

Joanna Debicka

Ekonometria > 2011 > 30 (Zastosowania metod ilościowych) > 106-120

Multistate insurance is a contract that covers different life accidents. This type of insurances consists of the core insurance contract (usually it is a life insurance) and a package of additional contracts (so called options for example health or disabled insurances).

A firm choosing among various solutions in working capital needs to decide what level of risk is acceptable for its owners and capital suppliers. That choice results in financial consequences, especially in the cost level.

THEORY OF EFFICIENCY MEASUREMENT IN MARKETING RESEARCH WITH REGRESSION AND STRUCTURAL EQUATIONS MODELS (Teoria pomiaru efektywnosci badan marketingowych w modelu regresji i rownan strukturalnych)

Piotr Tarka

Ekonometria > 2011 > 30 (Zastosowania metod ilościowych) > 70-82

Decision making by managers that is based on inefficient and ineffective marketing research may do harm putting a firm at risk. The minimization of such a risk is possible when an appropriate selection of analytical models is conducted, allowing a firm to measure the level and structure of efficiency related to marketing research expenditures and the real effects (economic results). In the first part...

LINEAR ORDERING WITH GENERALISED DISTANCE MEASURE GDM2 FOR ORDINAL DATA AND PROGRAM R (Porzadkowanie liniowe z wykorzystaniem uogolnionej miary odleglosci GDM2 dla danych porzadkowych i programu R)

Marek Walesiak

Ekonometria > 2011 > 30 (Zastosowania metod ilościowych) > 9-18

The article presents linear ordering methods based on ordinal data. New proposals for transformation formula of the variable values, which have nominant character of type, into destimulant variable are discussed (such transformation formulas are well known in literature for metric data). The last part of the article contains the application of the new function pattern.GDM2 of clusterSim package for...

CORRESPONDENCE ANALYSIS AS THE DIAGNOSTIC TOOL IN CASE OF MACROECONOMIC DATA (Analiza korespondencji jako narzedzie diagnostyczne w makroskali)

Katarzyna Wawrzyniak

Ekonometria > 2011 > 30 (Zastosowania metod ilościowych) > 19-27

The aim of the article is the application of simple correspondence analysis in order to evaluate the economic situation of voivodeships in Poland in 2007. Because of a small sample the procedure of doubling was used in the research. The empirical values of variables were replaced by ranks and on this base the anti-variables were created. The final diagnosis was formulated by means of the graphic presentation...

CONSENSUS METHODS FOR INCOMPLETE ORDERED COVERINGS (Metody consensusu w odniesieniu do niepelnych pokryc uporzadkowanych)

Jadwiga Sobieska-Karpinska, Marcin Hernes

Ekonometria > 2011 > 30 (Zastosowania metod ilościowych) > 121-129

Consensus methods for solving conflicts in incomplete ordered coverings are presented in this paper. The incomplete ordered coverings are expert information structures in many cases. This structure should be useful when an expert classifies all elements of a set in such a way that every element belongs to one class or to many classes. The consensus methods are one of the methods for solving knowledge...
