Analysis of transient emission curves by a convolved autoregressive model

A new method is developed for estimating the decay parameters of transient emission curves convolved with an instrumental response function. This method is based on the convolved autoregressive model, which we originally proposed. The computation time of the method is much shorter than that of the conventional nonlinear least-squares method. Results of analyses for simulated and real data are shown to demonstrate a high potential of the developed method.
