 Abstract

In this working report we outline how to determine the intermittency parameters gj from the activity matrix A (context: DX’08 paper Abreu, Zoeteweij, Van Gemund). We start with the single fault (SF) case and show that averaging over the error vector e is the exact way. We also show that in this way the probability of obtaining exactly this e vector in A is optimal. This is the key insight that allows us to determine g in the general multiple-fault (MF) case. We formulate the gj problem as a (probability) maximization problem, which we solve using a simple gradient ascent technique.
