Devices and methods for use in forecasting the state of one or more of a plurality of variables within a domain are provided. One example method includes determining, at a processor, a first probability curve indicative of a probability of a change-in-state of the first variable over a first interval, the first probability defining a first substantially continuous time trajectory, determining, at the processor, a second probability curve indicative of a probability of a change-instate of the second variable over a second interval, the second probability defining a second substantially continuous time trajectory, the first interval at least partially overlapping with the second interval, and displaying, at a display device, the first and second probability curves substantially in real time, thereby permitting a user to compare the relative probabilities of the change-in-state of at least one of the first and second variables.
