"WebWe can describe a projection as a linear transformation T which takes every vec tor in R2 into another vector in R2. In other words, T : R2 −→ R2. The rule for this mapping is that every vector v is projected onto a vector T(v) on the line of the projection. Projection is a linear transformation. Deﬁnition of linear " - Onto linear algebra

In statistics, the projection matrix , [1] sometimes also called the influence matrix [2] or hat matrix , maps the vector of response values (dependent variable values) to the vector of fitted values (or predicted values). It describes the influence each response value has on each fitted value.
