平均或标准差，通常计算了信号的分析，整体的一部分。但是，有时我们想知道这个数量在不断变化的数据流。 MEANSTDF计算预期的平均值和标准偏差值使用定义为每一个用户的数据的位置窗口。输出可能是有用的，而非线性趋势化和平稳性分析。-Mean or standard deviation are usually computed for whole part of the analysed signal. However, sometimes we would like to know how this quantities are changing in the data flow. MEANSTDF compute the expected mean and standard deviation values using user defined window for every data position. The output can be useful while nonlinear detrending or stationarity analysis.
