In the United States, the T-bone has the meat-cutting classification IMPS 1174; the porterhouse is IMPS 1173. In British usage, followed in Commonwealth countries, porterhouse refers to the strip steak side of a T-bone steak, while the tenderloin side is called the fillet.
In set theory, an ordinal number, or ordinal, is one generalization of the concept of a natural number that is used to describe a way to arrange a collection of objects in order, one after another. Any finite collection of objects can be put in order just by the process of counting: labeling the objects with distinct whole numbers.
As a predictive analysis, ordinal regression describes data and explains the relationship between one dependent variable and two or more independent variables. In ordinal regression analysis, the dependent variable is ordinal (statistically it is polytomous ordinal) and the independent variables are ordinal or continuous-level (ratio or interval). Sometimes the dependent variable is also called response, endogenous variable, prognostic variable or regressand.
