Description copied from class: AbstractTimePredictor

Computes some stats by running a Monte Carlo simulation of the process.

Specified by:

getPredictionStats in class AbstractTimePredictor

Parameters:

model - the model that is enriched by some training data

observedEvents - the current history of the trace (observed events so far)

currentTime - the current time at prediction

useOnlyPastTrainingData - indicator that tells us whether to only rely on training data that was observed in the past (relative to the currentTime)

semantics - the semantics with the current marking of the model that shows the starting point

Returns:

DescriptiveStatistics gathered from a set of simulated continuations of the current process
