A Julia wrapper for fitting Lasso and ElasticNet GLM models using the glmnet Fortran library.
GLMNet.jl is a Julia package that wraps the glmnet Fortran library to fit Lasso and ElasticNet regularization paths for generalized linear models. It solves problems in high-dimensional statistics by performing feature selection and regularization across linear, logistic, multinomial, Poisson, and Cox models. The package computes entire solution paths efficiently, allowing users to analyze how coefficients change with regularization strength.
Data scientists, statisticians, and researchers working in Julia who need robust regularization methods for regression and classification tasks, particularly those dealing with high-dimensional data or seeking interpretable models through feature selection.
Developers choose GLMNet.jl for its direct interface to the battle-tested glmnet Fortran implementation, ensuring numerical stability and performance. It provides a comprehensive set of GLM families and cross-validation tools within Julia's ecosystem, making it a reliable choice for statistical modeling without sacrificing speed.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Wraps the optimized glmnet Fortran library, ensuring numerical stability and reliable performance for large-scale problems, as highlighted in the README.
Supports multiple GLM families including linear, logistic, multinomial, Poisson, and Cox models, with built-in cross-validation for automatic λ tuning via glmnetcv.
Allows fine-tuning with options like weights, penalty factors, constraints, and standardization, providing control over model fitting and regularization paths.
Seamlessly integrates with Julia packages like Plots and DataFrames for visualization and data manipulation, as shown in the README examples.
Relies on Fortran code, which can complicate installation, debugging, and portability compared to pure Julia alternatives, potentially limiting transparency.
The README notes that Lasso.jl often achieves better performance, indicating this wrapper may not be the fastest option in all cases within Julia.
The README points to external files like readmeExamples.jl for exact reproduction, suggesting documentation might be sparse or require additional effort to follow.
Only implements Lasso and ElasticNet paths via glmnet, lacking support for newer regularization methods or variants beyond the Fortran library's capabilities.
