WebbA time series is a single set of data whose observations are ordered in time. The important difference with time series data is that the observations relate to a single quantity measured at a number of points in time. Therefore observations that are close in time are likely to be correlated and not independent. WebbA value of = indicates that the failure rate is constant over time.
