  "Description": "Extend lasso and elastic-net model fitting for large data\nsets that cannot be loaded into memory. Designed to be more\nmemory- and computation-efficient than existing lasso-fitting\npackages like 'glmnet' and 'ncvreg', thus allowing the user to\nanalyze big data with limited RAM <doi:10.32614/RJ-2021-001>.",
