Program and Data Files

This program replicates the empirical work reported in the above paper.

The file contains code to estimate threshold autoregressions and compute tests for the presence of threshold effects.

There is an F test of one regime against two regimes.
There is an F test of one regime against three regimes.
There is an F test of two regime against three regimes.
The p-values are calculated using asymptotic simulations and bootstrap methods.
