An analysis device including a substitution unit for substituting each event in an impulse-like event series with rectangular windows; a dividing unit for dividing the event series timewise at least at one transition point in the rectangular windows; a state vector generation unit for generating a state vector corresponding to the state of the rectangular windows in response to each of the divided time periods; and an analysis unit for performing Poisson regression using the state vectors corresponding to the time periods. A method comprising computer-executable steps is provided that substitutes each event in the inputted event series with rectangular windows; divides the event series timewise at least at one transition point in the rectangular pulses; generates a state vector corresponding to the state of the rectangular pulses in response to each of the divided time periods; and performs a Poisson regression using the state vectors corresponding to the time periods.
