The basis/mean is the equivalent to the pine built in function wma(). It assigns greater weighting to recent data points and less weighting on past data points. The weighted moving average is calculated by multiplying each observation in the data set by a predetermined weighting factor.
Similarly the stdev is calculated using the same weighting factors where recent deviations are given greater weight than past deviations.
