Abstract : Applications of characteristic functions to problems of theoretical statistics are considered. Some multivariate distributions which occur in statistical problems are studied, and the… Expand

E(Y) = flo +/3lE(X) + ... +4kE(Xk). (1.2) If k 2 and f2 t 0 (k = 1 and Ih1 + 0) then we speak of quadratic (linear) regression. If k = 0, that is if E( YjX) = E( Y) almost everywhere, then we say… Expand
