The thesis aimed to determine the most accurate model for classifying kidney failure patients by comparing linear discriminant analysis and binary logistic regression, and to identify the most significant variables affecting the classification of patients into acute or chronic kidney failure cases.
The findings revealed that both models achieved high levels of accuracy in correctly classifying the study data, with a slight relative advantage in favor of linear discriminant analysis. The results also showed that the most influential variables in patient classification were creatinine levels, white blood cell count, red blood cell count, and potassium levels.
The study recommended adopting the linear discriminant analysis model as a supportive tool for physicians in diagnosing kidney failure cases and utilizing the binary logistic regression model to interpret the probabilistic weights of the influential variables, while focusing on the key biological indicators identified by the study.
The defense session was attended by a number of academics, researchers, students, colleagues, and the researcher’s family.
