Encompasses the idea of a*straight line*in Euclidean geometry - MulticollinearityMulticollinearityMulticollinearity is a statistical phenomenon in which two or more predictor variables in a multiple regression model are highly correlated. In this situation the coefficient estimates may change erratically in response to small changes in the model or the data...

, a statistical phenomenon in which two or more predictor variables in a multiple regression model are highly correlated - Colinear mapColinear mapIn coalgebra theory, the notion of colinear map is dual to the notion for linear map of vector space, or more generally, for morphism between R-module. Specifically, let R be a ring, M,N,C be R-modules, and...
