The LASSO is capable of producing a “sparse” estimate of the parameter and can be used effectively even when the number of parameters exceeds the number of observations. LASSO estimates can be computed very efficiently using a number of methods, including coordinate descent methods. A number of generalizations of the LASSO have been proposed, including the fused LASSO, the group LASSO, and the adaptive LASSO.</jats:p>","journal":"Wiley StatsRef: Statistics Reference Online","year":2015,"id":46144,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":214447,"name":"Keith Knight","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"31712217","pmcid":null,"openalex_id":"https://openalex.org/W4256576576","authors":[],"funders":[],"total_grants":0,"fwci":null,"citation_percentile":null,"influential_citations":0,"citation_trend":[],"oa_status":"closed","license":"http://doi.wiley.com/10.1002/tdm_license_1.1","oa_locations":[{"url":"https://onlinelibrary.wiley.com/doi/pdf/10.1002/9781118445112.stat07543.pub2","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/full-xml/10.1002/9781118445112.stat07543.pub2","host_type":"publisher"},{"url":"https://doi.org/10.1002/9781118445112.stat07543.pub2","host_type":"journal"}],"fields_of_study":["Soil Geostatistics and Mapping","Advanced Statistical Methods and Models","Statistical and numerical algorithms"],"mesh_terms":[],"keywords":["Lasso (programming language)","Elastic net regularization","Coordinate descent","Linear regression","Shrinkage","Mathematics","Selection (genetic algorithm)","Set (abstract data type)","Algorithm","Regression","Ridge","Computer science","Statistics","Applied mathematics","Artificial intelligence","Biology"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-07T02:02:47.785778Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
