TIME SERIES MODELLING, INFERENCE AND …

TIME SERIES MODELLING, INFERENCE AND FORECASTING ... A time series process is a stochastic process or a collection of random variables yt indexed in time. Note that yt will be used throughoutthe book to denote a random variable or an actual realisation of the time series process at time t. We use the

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
