In this tutorial, we will use SPADE to detect the simplest type of such patterns, synchronous events that are found across a subset of the neurons considered (i.e., patterns that do not exhibit a *temporal extent*). We will demonstrate the method on stochastic data in which we control the patterns statistics. In a first step, let use generate 10 random spike trains, each modeled after a Poisson statistics, in which a certain proportion of the spikes is synchronized across the spike trains. To this end, we use the `compound_poisson_process()` function, which expects the rate of the resulting processes in addition to a distribution `A[n]` indicating the likelihood of finding synchronous spikes of a given order `n`. In our example, we construct the distribution such that we have a small probability to produce a synchronous event of order 10 (`A[10]==0.02`). Otherwise spikes are not synchronous with those of other neurons (i.e., synchronous events of order 1, `A[1]==0.98`).
