In this case lambda is 6, lambda+ is 8 and lambda- is 4.
Further it calls the lambda, which eventually calls DisplayIfEven lambda.
The last parameter is a function object, which I define as a lambda expression.
Now it seems clear to me that lambda is an onion: Alonzo Church himself wouldn't have used it if he had to write out the word lambda each time.

Therefore 1995 as the pivot year in the cusum chart is not cherry-picked, it emerges from the assumptions used to create the chart: lambda = 6, lambda+ = 8, lambda- = 4 and ARL greater than 400. k+ is then 7 and k- is 5.
