mTopN

mavgTopN	Within a sliding window of given length (measured by the number of elements), the function stably sorts X by S in the order specified by ascending, then calculates the average of the first top elements.
mbetaTopN	Within a sliding window of given length (measured by the number of elements), the function stably sorts X and Y by S in the order specified by ascending, then calculates the coefficient estimate ordinary-least-squares regressions of Y on X.
mcorrTopN	Within a sliding window of given length (measured by the number of elements), the function stably sorts X and Y by S in the order specified by ascending, then calculates the moving correlation of the first top pairs of elements in X and Y.
mcovarTopN	Within a sliding window of given length (measured by the number of elements), the function stably sorts X and Y by S in the order specified by ascending, then calculates the moving covariance of the first top pairs of elements in X and Y.
