This paper presents a Monte Carlo method for analyzing the space of trajectories entailed by a qualitative differential equation and deriving statistical properties of qualitative behaviors. Estimates of the occurrence probability of behaviors and estimates of parameters defined over numerical trajectories can be computed and used in several ways. For example, behavior probability can be used t...

BACKGROUND Sampling methods have proven to be a very efficient and intuitive method to understand properties of complicated spaces that cannot easily be computed using deterministic methods. Therefore, sampling methods became a popular tool in the applied sciences. RESULTS Here, we show that sampling methods are not an appropriate tool to analyze qualitative properties of complicated spaces u...
