Statistical Analysis of Pulse Processesgle pulse are not significant or of preminent interest, but we consider only the time occurrences of the pulses and we can look for periodicities, swarming, or correlation with other physical variables. This is the case of, e.g., the large pulses of gravitational antennas, the periodicities of which

Application of Bootstrap Sampling in γ-Ray Astronomy: Time Variability in Pulsed Emission from Crab e such scheme is called the bootstrap and fits very well for many astronomical applications. It is based on the well-known sampling plan called “sampling with replacement”. Digital computers make the method very practical for the investigation of various trends present in a limited set of data which

Binary Slice Fit Ellipticity Analysis the various sections are needed in the quantitative astrophysics of galaxies, globular star clusters, and other extended objects. The methods used come from the morphological characterization of the objects. The ellipse best-fit of isophotes is used for objects, like galaxies, that approximate the
