Abstract:
We consider the problem of studying the properties of the function Φ(T)(x, y) which corresponding to analysis of time series by using data window in two different cases; the first in discrete time series and the other in continuous time series. Some examples for the function Φ(T)(x, y) and data window are discussed.
