Piecewise-constant Poisson process rate functions are easy to estimate and provide easy random-process generation. When the true rate function is continuous, however, a piecewise-constant approximation is sometimes unacceptably crude. Given a non-negative piecewise-constant rate function, we discuss SMOOTH (Smoothing via Mean-constrained Optimized-Objective Time Halving), a quadratic optimization formulation that yields a smoother non-negative piecewise-constant rate function having twice as… CONTINUE READING
