INFLUENCE OF INTEGRATOR PARAMETERS ON ESTIMATES CALCULATED WITH THE STATISTICAL-MODEL OF OVERLAP

The effect of the slope and area thresholds of a digital integrator on the calculation of component numbers with the statistical model of ov erlap (SMO) is critiqued. As these thresholds increase, the numbers of maxima recognized by the integrator and components calculated with th e SMO both decrease. With modest changes in threshold, the maxima and component numbers decrease proportionally, such that their ratio remai ns constant. For larger changes in threshold, the number of components usually decreases more rapidly than the number of maxima. Computer si mulations are developed that confirm the general trend of these observ ations. The implications of these variations are discussed.
