Multifractal analysis is the mathematical study of the irregularity of objects or irregular functions. The two main classes of processes where multifractal analysis was performed are multiplicative processes (Mandelbrot cascades and their generalizations) and additive processes (Lévy processes, random wavelet series and their generalization). An important additive process is the random sum of pulses. These series are random sums of translations and dilatations of pulses supplied by a pulse of arbitrary form. The translation, expansion and amplitude parameters can be random (or deterministically related). Special cases of this model were introduced by Lovejoy and Mandelbrot to model the precipitations at a given point and further extensions...
