Tibshirani: regression shrinkage and selection via the lasso

What changed

Introduced the lasso for linear-model estimation, constraining the sum of absolute coefficient values so that some coefficients become exactly zero while retaining shrinkage stability.

Scientific scope

The record is the exact 1996 Journal of the Royal Statistical Society Series B paper. Its 1994 technical-report precursor, basis pursuit, later generalized lasso methods and subsequent theory remain separate.
