In statistics and information theory, the expected formation matrix of a likelihood function L(θ) is the matrix inverse of the Fisher information matrix of L(θ), while the observed formation matrix of L(θ) is the inverse of the observed information matrix of L(θ). Currently, no notation for dealing with formation matrices is widely used, but in books and articles by Ole E. Barndorff-Nielsen and Peter McCullagh, the symbol jⁱʲ is used to denote the element of the i-th line and j-th column of the observed formation matrix.
