You could try to zip your data file and see whether there is a change in
file size that you feel is significant in which case the series is not
random (-:
... after converting the -1s and 1s to bits, of course.

Does anyone know of a simple test
in any R package that given
a series of negative ones and positive
ones ( no other values are possible in the series )
returns a test of whether the series is random or not.
( a test at each point would be good but
I can use the apply function to implement
that )
on informational entropy here:

And if you do find a test in R, I would be interested as well.
Best,
Robert
