    R packages are collections of functions, documentation, and data that expand R. [16] For example, packages add report features such as RMarkdown, Quarto, [17] knitr and Sweave. Packages also add the capability to implement various statistical techniques such as linear, generalized linear and nonlinear modeling, classical statistical tests ...

    "Glmnet: Lasso and elastic-net regularized generalized linear models" is a software which is implemented as an R source package and as a MATLAB toolbox. [ 10 ] [ 11 ] This includes fast algorithms for estimation of generalized linear models with ℓ 1 (the lasso), ℓ 2 (ridge regression) and mixtures of the two penalties (the elastic net ...

    R 2 L is given by Cohen: [1] =. This is the most analogous index to the squared multiple correlations in linear regression. [3] It represents the proportional reduction in the deviance wherein the deviance is treated as a measure of variation analogous but not identical to the variance in linear regression analysis. [3]
