Some results on ℓ1 polynomial trend filtering

Yamada, Hiroshi; Du, Ruixue - In: Econometrics : open access journal 6 (2018) 3, pp. 1-10

ℓ1 polynomial trend filtering, which is a filtering method described as an ℓ1-norm penalized least-squares problem, is promising because it enables the estimation of a piecewise polynomial trend in a univariate economic time series without prespecifying the number and location of knots. This...
