In a recent post I highlighted a new EViews Add-in package, written by Itamar Caspi. His rtdaf package facilitates the application of the Right-Tail Augmented Dickey-Fuller tests that are "....designed to detect the presence of an unobserved bubble component in an observed asset price and to date-stamp its occurrence".
In part, the testing procedures are based on Phillips et al. (2013b). If you're following this literature, there are two other recent papers by those authors that are a must-read - Phillips et al. (2013,a,b)
