A Non-Gaussian Model for Time Series with Pulses
提出一种非高斯自回归模型,用于描述偶尔大幅增长(脉冲)且脉冲间呈指数衰减的时间序列,并开发了基于似然的推断方法,应用于内分泌学数据。
Abstract A non-Gaussian autoregressive-like model is presented for time series that exhibit occasional large increases in value, termed pulses, and exponential decay between pulses. The model differs from a first-order autoregressive process in its incorporation of feedback between the distribution of the current innovation and the history of the process. Likelihood-based methods of inference for the model are developed, and an application to endocrinological data is given.
