in the present study, quantitative relationships between molecular structure and anti-tubercular activity of some 5-methyl/trifluoromethoxy-1 h -indole-2,3-dione-3-thiosemicarbazone derivatives were discovered. the detailed application of an efficient linear method and principal component regression (pcr) for the evaluation of quantitative structure activity relationships of the studied compound...

The goal of combining the predictions of multiple learned models is to form an improved estimator. A combining strategy must be able to robustly handle the inherent correlation, or multicollinearity, of the learned models while identifying the unique contributions of each. A progression of existing approaches and their limitations with respect to these two issues are discussed. A new approach, ...

The aim of this paper is the imputation missing data COVID-19 hospitalized and intensive care curves in several Spanish regions. Taking into account that cases, deceases recovered people are completely observed, a function-on-function regression model proposed to estimate values functional responses associated with curves. estimation coefficient terms principal components’ observed provides pre...
