This note presents models for mixture-amount experiments when the total amount takes a zero value. These models modify those of Piepel and Cornell (1985), which are ...

Our body's "blood factory" consists of specialized tissue made up of bone cells, blood vessels, nerves and other cell types.

When a spacecraft enters a thick atmosphere at a high velocity, it rapidly compresses the gas in front of it. This creates temperatures high enough to ionize the gas molecules into a hot, dense plasma ...

In this module, we will introduce generalized linear models (GLMs) through the study of binomial data. In particular, we will motivate the need for GLMs; introduce the binomial regression model, ...

THE STANDARD MODEL of particle physics—completed in 1973—is the jewel in the crown of modern physics. It predicts the properties of elementary particles and forces with mind-boggling accuracy. Take ...

How did science get started? A few years back, we looked at one answer to that question in the form of a book called The Invention of Science. In it, British historian David Wootton places the origin ...
