I'm looking for a standard name in the math world for a sequence, which has some base subtracted, where the base is close to the average. There is an example:
Assume there is a sequence with the first ten elements: 9, 7, 4, 0, 5, 7, 3, 0, 8, 1, .... The average of the first five 5 9, 7, 4, 0, 5 is 5. Let's name this the base since all these and other numbers, appearing in the sequence are about five, and this value will not be changed further.
The source sequence with the base subtracted is 4, 2, -1, -5, 0, 2, -2, -5, 3, -4, ...
Whether there is a standard coined name for this conversion, like *centered sequence *, sequence off by approximate mean or anything else?
