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.
To produce the graph in #43 I used the Excel spreadsheet sspois.xls found here from Hawkins and Olwell of the University of Minnesota and based on their book “Cumulative Sum Charts and Charting for Quality Improvement” with lambda =5.5, lambda+ = 9 and lambda- = 2.
In this case lambda is 6, lambda+ is 8 and lambda- is 4.
We then create a variable name for the generated code to hold the new lambda expression in, making sure that it will be unique by prefixing it with lambda_ (ugly, I know).
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.
Further it calls the lambda, which eventually calls DisplayIfEven lambda.
So, here we call the lambda, sending it 4 as the first argument (which is assigned to n), and a block (which is converted and assigned to name).
The say hello lambda does its work, invoking the name lambda (with no arguments) in turn.
In the 20's, Hubble and some other astronomers discovered the expansion of space so Einstein said "Oh, away with the cosmological constant," and never wanted to talk about it again and now in 1998 when the discovery was made that the universe is expanding faster all the time, lambda came back because mathematically the same type of constant, which is called lambda can make the universe expand faster.
