This research investigates how to determine whether two rankings come from the same distribution. We evaluate three hybrid tests: Wilcoxon’s, Dietterich’s, and Alpaydin’s statistical tests combined with cross-validation (CV), each operating with folds ranging from 5 to 10, thus altogether 18 variants. We have applied these tests in the framework of...

Given a weakly stationary, multivariate time series with absolutely summable autocovariances, asymptotic relation is proved between the eigenvalues of the block Toeplitz matrix of the first n autocovariances and the union of spectra of the spectral density matrices at the n Fourier frequencies, as n → ∞. For the proof, eigenvalues and eigenvectors...
Article
Studying the effectiveness of remedial courses in higher education has attracted a lot of interest from educational researchers and practitioners. Remediation is associated with significant economic and social costs while the results are usually dubious. In this paper, we apply a widely used method called Regression Discontinuity Design (RDD) to me...

Constructions for regression graphs and verification of the statistical model via linear, linearized, and logistic regressions along them have recently been intensively studied. Given the graph, an iterative regression method, using local averaging estimators, is introduced for prediction, based on a complete training sample. The method makes it po...

Article
This versatile topic goes back to the inventions of Gauss, Markov, and Gibbs, whose ideas are incorporated in graphical models and regression graphs. Later, the geneticist S. Wright (1923–1934) and the philosopher and computer scientist J. Pearl (1986–1987) developed the tools, but their notation is too complicated to formulate the mathematical bac...
