[Gretl-users] Package updates (February 2026)

Dear all, this message is to inform the community about the activity in our function package repository: during the month of February 2025, 3 packages were updated to a new version and a new one was released. The new one is "ZivotAndrews", by myself, which implements Zivot and Andrews' famous unit-root test under structural breaks. Notably, it features a novel method for computing p-values, which is described here <https://doi.org/10.1016/j.econlet.2026.112833>;. The updates were: "paneldesc", also by myself (Basic statistics about gaps in panel datasets) "CSDpanel", by Sven Schreiber and Jörg Breitung (test and estimators for panel datasets with cross-section dependence) "TVC", by Ekkehart Schlicht (Regression with Time-varying coefficients using this estimator <https://link.springer.com/article/10.1007/s42952-021-00110-y>) Moreover, a companion package to TVC, "TVCplots" was released yesterday. As usual, update and enjoy! ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
