recommendations! Published in 2024 at "Journal of Mathematics"

DOI: 10.1155/2024/6694880

Abstract: In the field of chemical data modeling, it is common to encounter response variables that are constrained to the interval (0, 1). In such cases, the beta regression model is often a more suitable choice… read more here.

DOI: 10.15672/hujms.1544513

Abstract: Cook’s distance is one of the renowned and classic tools for the detection of influential observations. In this article, we propose to use Cook’s distance with different residuals in the Beta regression model, which is… read more here.

DOI: 10.3390/axioms12060526

Abstract: The beta regression model (BRM) is used when the dependent variable may take continuous values and be bounded in the interval (0, 1), such as rates, proportions, percentages and fractions. Generally, the parameters of the… read more here.
