WebUse Fisher's exact test to analyze a 2x2 contingency table and test whether the row variable and column variable are independent (H 0: the row variable and column variable are independent). The p-value from Fisher's exact test is accurate for all sample sizes, whereas results from the chi-square test that examines the same hypotheses can be ... WebUnit root and stationarity test statistics have nonstandard and nonnor-mal asymptotic distributions under their respective null hypotheses. To complicate matters further, the limiting distributions of the test statistics are aﬀected by the inclusion of deterministic terms in the test regressions. http://fabian-kostadinov.github.io/2015/01/27/comparing-adf-test-functions-in-r/ ch the rattrap class 12

http://www.fisherlab.com/hobby/field-tests.htm In statistics, an augmented Dickey–Fuller test (ADF) tests the null hypothesis that a unit root is present in a time series sample. The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity. It is an augmented version of the Dickey–Fuller test … See more The testing procedure for the ADF test is the same as for the Dickey–Fuller test but it is applied to the model where $${\displaystyle \alpha }$$ is a constant, See more • In R, there are various packages supplying implementations of the test.
