detrend
To remove the general drift, tendency, or bent of a set of statistical data as related to time. Often accomplished by regressing ( regression) a variable or a time index and perhaps the square of the time index and capturing the residuals. A stochastic detrend would be to subtract a moving-average (say for five years) from the value of the variable. Bloomberg Financial Dictionary
