Published in 2017 at "Communications in Statistics - Theory and Methods"

DOI: 10.1080/03610926.2017.1295075

Abstract: ABSTRACT In this paper, a generalized difference-based estimator is introduced for the vector parameter β in partially linear model when the errors are correlated. A generalized-difference-based almost unbiased two-parameter estimator is defined for the vector… read more here.

Published in 2022 at "Epidemiology"

DOI: 10.1097/ede.0000000000001568

Abstract: Difference-in-differences (DID) analyses are used in a variety of research areas as a strategy for estimating the causal effect of a policy, program, intervention, or environmental hazard (hereafter, treatment). The approach offers a strategy for… read more here.

Published in 2020 at "Symmetry"

DOI: 10.3390/sym12111816

Abstract: Our investigation is motivated essentially by the demonstrated applications of the basic (or q-) series and basic (or q-) polynomials, especially the basic (or q-) hypergeometric functions and basic (or q-) hypergeometric polynomials, in many… read more here.
