1 What is a Time Series. A set of observed values ordered in time, or we can say, repeated measurement of something usually with the same fixed interval of time (hourly, weekly, monthly). A collection of observations made sequentially in time [ 1]. If the variable we are measuring is a count variable, we may have a Poisson Time Series (that is ...

The term “localise” has two relevant interpretations here.
