Introduction
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)
Statistical Tests Based on Empty Cells
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)
In professional literature on statistics, a constantly growing interest is observed in
non-parametric methods. Commonly these methods are based on counting, rank or position statistics
and on a number or length of series. ...
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 ...
Using Permutation Tests in Multiple Correlation Investigation
(Wydawnictwo Uniwersytetu Łódzkiego, 2012)
An indication of correlation between dependent variable and predictors is a crucial
point in building statistical regression model. The test of Pearson correlation coefficient – with
relatively good power – needs to ...
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 ...
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, ...
