- An Upstate New York business machine company used to include a random
number generator called RANDU in its software library. This generator
was supposed to produce numbers that behaved like i.i.d. uniform
random variables. The data set randu in the file "2D randu.lsp in
the Data folder consists of a list of three lists of
numbers. These lists are consecutive triples of numbers produced by
RANDU. Use "2D spin-plot to see if you can spot any unusual
features in this sample.
