KKK autocorrelation coefficient is equal to 3, which represents a measure of the correlation coefficient stationary series TTT TTT33, as to the middle PPP333 coefficient of us can ignore.
Is the KKK equals the self-correlation coefficient of 3, which represents the coefficient of measuring the smooth sequence TTT and TTT33, which we can ignore as far as the coefficient of the middle PPP333 is concerned.
It is the autocorrelation coefficient when KKK is equal to 3. It represents the correlation coefficient of TTT and ttt33, and we can ignore the coefficient of ppp333 in the middle.
