The affine matrix
WebProve that the BLUE commutes over linear (actually affine) transformations of x. Thus, if we wish to determine y = B + b where B is a known p × p invertible matrix and b is a known p × 1 vector, prove that the BLUE is given by y ^ = B x ^ + b where x ^ is the BLUE for x. The similarity transformations form the subgroup where is a scalar times an orthogonal matrix. For example, if the affine transformation acts on the plane and if the determinant of is 1 or −1 then the transformation is an equiareal mapping. Such transformations form a subgroup called the equi-affine group. See more In Euclidean geometry, an affine transformation or affinity (from the Latin, affinis, "connected with") is a geometric transformation that preserves lines and parallelism, but not necessarily Euclidean distances See more Let X be an affine space over a field k, and V be its associated vector space. An affine transformation is a bijection f from X onto itself that is an affine map; this means that $${\displaystyle g(y-x)=f(y)-f(x)}$$ well defines a linear map from V to V; here, as usual, the … See more Properties preserved An affine transformation preserves: 1. collinearity between points: three or more points which lie on the same line (called collinear points) continue to be collinear after the transformation. 2. parallelism: two or more lines which … See more The word "affine" as a mathematical term is defined in connection with tangents to curves in Euler's 1748 Introductio in analysin infinitorum See more By the definition of an affine space, V acts on X, so that, for every pair (x, v) in X × V there is associated a point y in X.

One approach consists on a semidefinite programming formulation (see [0], [00]), where nonlinearities caused by variable multiplications are replaced by a semidefinite matrix with rank one.
