    Application of the Polynomial Maximization Method for Estimating Nonlinear Regression Parameters with Non-Gaussian Asymmetric Errors
    (Springer Nature, 2024) Заболотній, Сергій Васильович; Zabolotnii, Serhii; Tkachenko, Oleksandr; Nowakowski, Waldemar; Warsza, Zygmunt Lech
    In the article, an alternative approach to estimating parameters in nonlinear regression models under asymmetric error distributions is examined. A novel approach for adaptive estimation is proposed, which is based on the use of second-order polynomial functions. This enables a straightforward implementation to account for deviations from Gaussian idealization in the form of moments up to the fourth order. It is demonstrated that the overall problem can algorithmically be reduced to the numerical solution of a system of nonlinear stochastic equations. Analytical expressions are obtained, which facilitate the estimation of parameters and the analysis of their asymptotic variance. Statistical modeling using the Monte Carlo method was conducted, and the results indicate that the accuracy of PMM2 estimates is comparable to SLS estimates and significantly so exceeds the accuracy of OLS estimates.

    Benefits of Human-Centered Digitalization in the Context of Ukrainian Labor Market
    (Publishing House "Baltija Publishing", 2024) Азьмук, Надія Анатоліївна
    The paper investigates changes in the resilience of Ukraine‘s labor market. The expediency of using digital technologies as a factor in strengthening the resilience of the social and labor sphere is substantiated. Changing the paradigm of digitalization on the basis of Industry 5.0 towards humancentered digitization is emphasized. The advantages of using humancentered digitalization to strengthen the resilience of social and labor spheres in the period of post-war recovery of Ukraine‘s national economy are determined.
