On the calculation of the generalizedQ-function via Parl's method (Corresp.) Academic Article uri icon


  • Parl has previously given error bounds suitable for calculating Marcum's Q-function. However, it is shown that additional terms in the error bound are necessary for accurate calculations of the generalized Q-function Qm(α, β). The values of m, α, and β that result in successful algorithm completion are examined. Numerical results are presented for calculations of the noncentral chi-square distribution and the probability of detection for a classical multiobservation detection problem.
