It seems clear that both age and gender have an e ect on someone’s survival, how do we come up with a model that will let us explore this relationship? Even if we set Died to 0 and Survived to 1, this isn’t something we can transform our way out of - we need something more. One way to think about the problem - we can treat Survived and Died as

Vector Autoregressive Models for Multivariate Time Series

Multivariate Time Series 11.1 Introduction The vector autoregression (VAR) model is one of the most successful, flexi-ble, and easy to use models for the analysis of multivariate time series. It is a natural extension of the univariate autoregressive model to dynamic mul-tivariate time series. The VAR model has proven to be especially useful for
