    Understanding the k lag in R's augmented Dickey …

    The k parameter is a set of lags added to address serial correlation. The A in ADF means that the test is augmented by the addition of lags. The selection of the number of lags in ADF can be done a variety of ways.

    What is the difference between K and a in ADF?

    What does a mean in ADF?
    The A in ADF means that the test is augmented by the addition of lags. The selection of the number of lags in ADF can be done a variety of ways. A common way is to start with a large number of lags selected a priori and reduce the number of lags sequentially until the longest lag is statistically significant.

    What is ADF test?
    The ADF test belongs to a category of tests called ‘Unit Root Test’, which is the proper method for testing the stationarity of a time series. So what does a ‘Unit Root’ mean? Unit root is a characteristic of a time series that makes it non-stationary.

    How to interpret ADF test results from R package?
    We explain the interpretation of ADF test results from R package by making the meaning of the alphanumeric name of test statistics clear. We have implemented a R code for the VAR model in the prior post below but have not discussed the ADF test specifically, which is the test for stationarity or nonstationary (unit root) of a given time series.

    What is the difference between unit root test and ADF test?
    Based on the Wikipedia page on the topic, those three ADF tests are almost the same in that the unit root test is carried out under the null hypothesis r = 0 against the alternative hypothesis of r < 0 and DF = r/SE (r). Is the only difference the critical value? The R function adf.test only uses one type of critical value (with drift and trend).

    What is lag length p in ADF?
    By including lags of the order p, the ADF formulation allows for higher-order autoregressive processes. This means that the lag length p must be determined in order to use the test. One approach to doing this is to test down from high orders and examine the t -values on coefficients.
