http://www.fsb.miamioh.edu/lij14/672_2014_s6.pdf WebThe Augmented Dickey-Fuller test is a type of statistical test called a unit root test. The intuition behind a unit root test is that it determines how strongly a time series is defined by a trend. There are a number of unit root tests and the Augmented Dickey-Fuller may be one of the more widely used.

WebWhy is unit root troublesome? • For one thing, the law of large number (LLN) does not hold for a unit root process. • For a stationary and ergodic process LLN states that as T → ∞ 1 T ∑T t=1 yt → E(yt) • Unit root may cause three troubles. First, E(yt) may not be a constant. Second, the variance of yt is non-constant. Third, the serial correlation between yt and yt j … WebIn statistics, the Dickey–Fuller test tests the null hypothesis that a unit root is present in an autoregressive (AR) time series model.
