A relational event history is determined based on a data set, the relational event history including a set of relational events that occurred in time among a set of actors. Data is populated in a probability model based on the relational event history, where the probability model is formulated as a series of conditional probabilities that correspond to a set of sequential decisions by an actor for each relational event, where the probability model includes one or more statistical parameters and corresponding statistics, and where at least one of the one or more statistics is determined using a decay function. A baseline communications behavior for the relational event history is determined based on the populated probability model, and, based on a second set of values for the statistical parameters, departures within the relational event history from the baseline communications behavior are determined.
