A t-test is an inferential statistic used in hypothesis testing to determine if there is a statistically significant difference between the means of two samples.

In this paper we produce a table of critical values of Mood's test statistic which may be used in the distribution-free comparison of the dispersions of two independent samples. As far as we know the ...

Response surface analysis is used to obtain approximate finite-sample critical values for the augmented Dickey-Fuller (ADF) test. Previous studies estimating the critical values for the test have ...
