NettetMulticollinearity refers to a situation in which more than two explanatory variables in a multiple regression model are highly linearly related. There is perfect multicollinearity if, for example as in the equation above, the correlation between two independent variables equals 1 or −1. In practice, perfect multicollinearity in a data set is ... A sequence of vectors from a vector space V is said to be linearly dependent, if there exist scalars not all zero, such that where denotes the zero vector. This implies that at least one of the scalars is nonzero, say , and the above equation is able to be written as paw patrol war and love fanfiction
