A variable star is, quite simply, a star that changes brightness. A star is considered variable if its apparent magnitude (brightness) is altered in any way from our perspective on Earth. These ...

Double and variable stars offer accessible observational targets from urban environments, as their concentrated light output allows them to penetrate light pollution more effectively than diffuse deep ...

What is Fisher's exact test? Fisher’s exact test is a statistical hypothesis test used to assess the association between two binary variables in a contingency table and is particularly useful when ...

A white dwarf has been cannibalizing a former sun-like star, resulting in their orbits around one another shortening to just 51 minutes. When you purchase through links on our site, we may earn an ...

This paper studies the special case of the triangular system of equations in Vytlacil and Yildiz (2007), where both dependent variables are binary but without imposing the restrictive support ...

Because machine learning with deep neural techniques has advanced quickly, our resident data scientist updates binary classification techniques and best practices based on experience over the past two ...
