    A VAR with p lags can always be equivalently rewritten as a VAR with only one lag by appropriately redefining the dependent variable. The transformation amounts to stacking the lags of the VAR(p) variable in the new VAR(1) dependent variable and appending identities to complete the precise number of equations.

    In the mathematical subject of geometric group theory, the Švarc–Milnor lemma (sometimes also called Milnor–Švarc lemma, with both variants also sometimes spelling Švarc as Schwarz) is a statement which says that a group , equipped with a "nice" discrete isometric action on a metric space, is quasi-isometric to .

  8. Fisher's exact test - Wikipedia

    en.wikipedia.org/wiki/Fisher's_exact_test

    We set up the following probability model underlying Fisher’s exact test. Suppose we have a + b {\textstyle a+b} blue balls, and c + d {\textstyle c+d} red balls. We throw them together into a black box, shake well, then remove them one by one until we have pulled out exactly a + c {\textstyle a+c} balls.
