Two-sample test of difference in probability mass at the extremes of the empirical distributions
I am running an experiment that will generate a dependent variable (DV) in two treatments, T1 and T2.
One of the hypotheses I want to test is whether the distribution of the DV in T1 has more mass at ...

Compare distributions using Maximum Mean Discrepancy (MMD)
I use MMD distance to run a permutation test and decide whether two sample distributions come from the same distribution or not. For the MMD, I use a gaussian kernel, the bandwidth of which I select ...

Is Kolmogorov-Smirnov test known to fail in some special cases?
I would like to use two samples Kolmogorov-Smirnov test to check if two given samples are coming from different distributions. For that I use scipy implementation of the KS test.
I have found out ...

Why is the distribution of d̄ normal? (d̄ = x̄₁ - x̄₂ when both sampling distributions are normal)
I'm learning about doing inference with two samples. $d̄ = x̄₁ - x̄₂$. Sampling is independent. Let's suppose $x̄₁$ and $x̄₂$ are both normally distributed. My understanding is that this means $d̄$ ...
