dfuller — Augmented Dickey–Fuller unit-root test - Stata

Dickey and Fuller(1979) developed a procedure for testing whether a variable has a unit root or equivalently that the variable follows a random walk Hamilton(1994 528–529) describes the four different cases to which the augmented Dickey–Fuller test can be applied The null hypothesis is always that the variable has a unit root

5 1 Dickey-Fuller Test We now apply the augmented Dickey-Fuller (ADF) test to the data sampleused by Holden and Perman [1994] The authors applied an integration/coin-tegration analysis to a consumption function for the United Kingdom usingquarterly data for the period 1966:Q4–1991:Q2

These authors motivate their test with a particular analogy with the Dickey-Fuller test whereas we interpret the FDF test as a class of tests indexed by an auxiliary parameter which can be chosen to maximize the power of the test Within this framework we investigate optimality aspects of the FDF test and show that the version of the test

What is the augmented Dickey-Fuller test?

The augmented Dickey-Fuller (or ADF) test is a com- monly used unit-root test. Fitting an (autoregressive) AR(k) model, this test examines the null hypothesis of an (autore-

Is there a constant and time trend in the augmented Dickey-Fuller regression?

This dataset has 144 observations on the monthly number of international airline passengers from 1949 through 1960. Because the data show a clear upward trend, we use the trend option with dfuller to include a constant and time trend in the augmented Dickey–Fuller regression.

When does k = 1 match with MacKinnon and Fuller?

values here with those reported by MacKinnon (1991) and Fuller (1976). In general, they are found to match closely with one another when k = 1. Consider the test with a time

How are critical values reported by dfuller interpolated?

The critical values reported by dfuller are interpolated based on the tables in Fuller(1996).MacKinnon(1994) shows how to approximate the p-values on the basis of a regression surface, and dfuller also reports that p-value.
