Prior Sensitivity Analysis in a Semi-Parametric Integer-Valued Time Series Model

Prior Sensitivity Analysis in a Semi-Parametric Integer-Valued Time Series Model

We examine issues of prior sensitivity in a semi-parametric hierarchical extension of the INAR(<i>p</i>) model with innovation rates clustered according to a Pitman&#8722;Yor process placed at the top of the model hierarchy. Our main finding is a graphical criterion that guides the s...
