A two-sample t-test compares significant or random differences between two samples. It is most useful for hypothesis testing, ...

In the Two-Sample Test for Proportions task, you can determine whether two probabilities are the same. The data analyzed in this example are taken from a study measuring the accuracy of two computer ...

of $\theta = 4$ for this test Note that if we had set $\alpha_r = 0.001$, we could never have conducted a two-sided test on this sample, since $\alpha(0)$, the $\alpha$ value for the smallest possible ...

A one-sample t-test is used to test whether the mean of a single population is equal to a specified value. For example, you might want to check if the average height of students in your class is ...

autotst is a Python package for easy-to-use two-sample testing and distribution shift detection. This allows you to change the time limit for fitting the witness function and you can also pass other ...

This web calculator conducts a z-test for the difference between two populations' proportions. The calculator includes an explanation of inputs and outputs. This web calculator conducts a z-test for ...

A pure Python implementation of one-sample t-test, paired samples t-test, and unpaired samples (independent samples or two-sample) t-test.

Abstract: We propose two statistical tests to determine if two samples are from different distributions. Our test statistic is in both cases the distance between the means of the two samples mapped ...
