Functions for analysis of panel data, including the panel threshold model of Hansen (1999,JE), panel unit root test of Chang(2002,JE) based upon instuments generating functions (IGF), and panel seasonal unit root test based upon Hylleberg et al.(1990,JE).
This version offers formatted output. This package designs a specification function ptm() to estimate the panel threshold model of Hansen(1999). The key feature of ptm() is to generalize Hansen's original code to allow multiple (more-than-one) regime-dependent right-hand-side independent variables; Dr. Hansen's original code admits only 1 regime-dependent right-hand-side independent variable. This version also includes panel unit root tests based on the instrument generating functions(IGF), proposed by Chang (2002, J. of Econometrics), and the panel version of Hylleberg et al.(1990) seasonal unit root test, proposed by Otero, et al. (2005, 2007).
