WebApr 4, 2016 · The submission considers first-order exponential-decay Hawkes processes with constant unconditional intensities, and presents a) a calculation of point-time … WebThis paper presents a parametric estimation method for ill-observed linear stationary Hawkes processes. When the exact locations of points are not observed, but only counts over time intervals of fixed size, methods based on the likelihood are not feasible. We show that spectral estimation based on Whittle’s method is adapted to this case and provides …
WebDec 20, 2011 · The Hawkes process is a practically and theoretically important class of point processes, but parameter-estimation for such a process can pose various problems. In this paper we explore and compare two approaches to Bayesian inference. WebI'm struggling with implementing the maximum likelihood estimator for a multivariate Hawkes process (HP). Specifically, while the analytical expression for a log-likelihood function of …
WebA basic issue in applications of Hawkes processes con-cerns their estimation. In early applications, parametric estimation used spectral analysis by means of the Bartlett spectrum (the Fourier transform of the autocovariance of the process) [4,5] and it was indeed through that light that Hawkes presented his model. A maximum likelihood WebThe aim of this paper is to provide a new method for the detection of either favored or avoided distances between genomic events along DNA sequences. These events are …
