2) can be called a noncentral generalized Laplace variable (NGL). f. 1) is called a noncentral gamma difference with the parameters (ab a2, /3b 132, Ab A2) and when Al = 0 = A2 it is called a central gamma difference. f. 2) will be called a noncentral generalized Laplacian (NGL) with the parameters (a, /3, A). When A = 0 it is called a generalized Laplacian or a central generalized Laplacian with the parameters (a, /3). 2) and their particular cases. 1). r2! 6) with aj replaced by aj + Tj, i = 1,2.

We will be mainly dealing with bilinear forms in random variables and particularly in singular and nonsingular Gaussian or normal random vectors. The distribution of a quadratic form in normal vectors reduces to that of a linear combination of independent central or noncentral chi-square random variables when the quadratic form is positive definite. What will be the corresponding result when dealing with bilinear forms? It will be shown later that they fall in the categories of gamma difference, Laplacian and generalized Laplacian.

1, -1, ... , -1, 0, ... ,. ,.. This completes the proof of necessity. Sufficiency can be seen by retracing the steps. 2 to be distributed as a noncentral chi-square difference with degrees of freedom v and noncentrality parameter ,\ are (i)d to (iV)d if B' AB is nonsingular and (i)d to (V)d if B' AB is singular, with s = v, f3 = 2. 5 The NS conditions for Q(Z) = X' B2 Y to be NGL are (i)d to (iV)d if B' AB is nonsingular and (i)d to (V)d if B' AB is singular with ""1 and""2 would take up Writing the conditions (i)d to (V)d in terms of B2, Lu, L22, too much space.
