Choosing the most appropriate model and distribution for each time series: This is a critical step to detect any outlier because time series can behave in various ways (stationary, non-stationary, irregularly sampled, discrete, etc), each requiring a different model of normal behavior with a different underlying distribution. What is the secret to KIPPs success? John Tukey, the great statistician, came up with the box and whisker plot, now usually called the boxplot, to visually express this idea.
