import { tTestTwoSample } from "https://deno.land/x/simplestatistics@v7.8.3/index.js";
This is to compute two sample t-test.
Tests whether "mean(X)-mean(Y) = difference", (
in the most common case, we often have difference == 0
to test if two samples
are likely to be taken from populations with the same mean value) with
no prior knowledge on standard deviations of both samples
other than the fact that they have the same standard deviation.
Usually the results here are used to look up a p-value, which, for a certain level of significance, will let you determine that the null hypothesis can or cannot be rejected.
diff
can be omitted if it equals 0.
This is used to reject
a null hypothesis that the two populations that have been sampled into
sampleX
and sampleY
are equal to each other.
