Design of an imputation methodology by random selection using regression trees

Bulletin of Computational Applied Mathematics, 2021
One of the biggest issues in the information collection stage is the absence of data, this research focuses specifically on the scenario when the loss is partial, completely random and the data is quantitative. There are classic techniques to impute data,

The Challenges of Chromosome Y Analysis and the Implications for Chronic Kidney Disease

Frontiers in Genetics, 2019
The role of chromosome Y in chronic kidney disease (CKD) remains unknown, as chromosome Y is typically excluded from genetic analysis in CKD. The complex, sex-specific presentation of CKD could be influenced by chromosome Y genetic variation, but there ...
