<b>exuber</b>: Recursive Right-Tailed Unit Root Testing with <i>R</i>

This paper introduces the R package exuber for testing and date-stamping periods of mildly explosive dynamics (exuberance) in time series. The computes test statistics supremum augmented Dickey-Fuller (SADF) Phillips, Wu, Yu (2011), generalized SADF (GSADF) Shi, (2015a,b), panel GSADF proposed by Pavlidis, Yusupova, Paya, Peel, Martínez-García, Mack, Grossman (2016); generates finite-sample critical values based on Monte Carlo bootstrap methods; implements corresponding procedures. recursive least-squares algorithm that we introduce our implementation these techniques utilizes matrix inversion lemma way achieves significant speed improvements. We illustrate gains a simulation experiment, provide illustrations using artificial series international house prices.
