Autoregressive conditional proportion: A multiplicative‐error model for (0,1)‐valued time series

Modelling Time Series Count Data: An Autoregressive Conditional Poisson Model

This paper introduces and evaluates new models for time series count data. The Autoregressive Conditional Poisson model (ACP) makes it possible to deal with issues of discreteness, overdispersion (variance greater than the mean) and serial correlation. A fully parametric approach is taken and a marginal distribution for the counts is specified, where conditional on past observations the mean is...

Time - series Econometrics : Cointegration and Autoregressive Conditional Heteroskedasticity

Autoregressive conditional root model

In this paper we develop a time series model which allows long-term disequilibriums to have epochs of non-stationarity, giving the impression that long term relationships between economic variables have temporarily broken down, before they endogenously collapse back towards their long term relationship. This autoregressive root model is shown to be ergodic and covariance stationary under some r...

Multivariate Modelling of Time Series Count Data: An Autoregressive Conditional Poisson Model

This paper introduces a new multivariate model for time series count data. The Multivariate Autoregressive Conditional Poisson model (MACP) makes it possible to deal with issues of discreteness, overdispersion (variance greater than the mean) and both autoand cross-correlation. We model counts as Poisson or double Poisson and assume that conditionally on past observations the means follow a Vec...
