Characterisation of PrasNikh–N Distribution and Its Biomedical Application

Abstract

Objectives: A new class of Two-parameter Akash distribution is proposed and termed PrasNikh-N Distribution (P2ND). Its various structural properties are derived and researched. Methods: The concept of weighted distributions is applied. The distribution parameters have been calculated by maximum likelihood estimation. Findings: The characterisation sketch of the distribution is analysed. To examine the significance and supremacy of the distribution, this is applied to a real lifetime medical data, consists of the weight loss (kilograms (Kg)) after the first cycle of chemotherapy, of randomly selected 60 patients from a hospital in Thrissur district, Kerala who were suffering from any type of gastrointestinal (GI) cancer. The goodness of fit is tested for the same. Novelty:The results are compared with the known distributions & indicate that the proposed distribution shows a better fit than the other distributions, and hence clarifies the significance of the new distribution.
