Without loss of generality, we assume that the quadratic form is normalized such that matrix H is symmetric, the neutral stimulus (usually an average or blank stimulus) is zero, and the response ...

The cumulants of a quadratic form in n independent standardized variables are identified with the traces of the powers of the matrix of the form. This identification leads to some very simple proofs ...
