a statistics expert, but he was also a beer expert. He monitored the quality of stout beer at the Guinness brewery in Dublin, Ireland. He wanted to be empirical about it, and he sort of randomly assigned different things to different batches and then, developed this test to comparemeans. ...

aRandom walks, characterized by an erratic change of an observable, occur at all length and time scales in a variety of systems. Examples are provided by atoms in magneto-optical traps; the diffusion of cellular components, such as DNA, proteins, lipids, and organelles; the motion of bacteria...
Mounting evidence supports the idea that transcriptional patterns serve as more specific identifiers of active enhancers than histone marks; however, the optimal strategy to identify active enhancers both experimentally and computationally has not been d

Qs = (T - E(T))2/ V(T) If you look at the formula for Qs, you see something interesting. It is simply Qs = (N - 1) * ray2 where rayis Pearson’s correlation coefficient for a and y. Just Pearson’s correlation This “test of trend” is nothing more than Pearson’s correla...
k-tuple count/frequency vector of each sample was first calculated, and samples were compared with each other using each dissimilarity measure. We then used the UPGMA method [43] to cluster the samples based on the dissimilarity matrix. The parsimony test [25] was finally used to compare the...
Multidimensional forced-choice (MFC) testing has been proposed as a way of reducing response biases in noncognitive measurement. Although early item respon
