Deviation

Occasionally I see a request for computation of a running, windowed standard deviation. This is easily accomplished using filter and the alternative formula for the standard deviation:std = sqrt((sum(x.^2) - n*xbar.^2)/(n-1)).Movingstd allows you to specify forward, backward or central windows of...

Statistical Calculator calculates minimum, maximum, mean, median, mode, percentage unique, range, midrange, standard deviation, quartiles and more.

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....

This m-file returns the mean, variance and standard deviation of the multinomial distribution with parameters N and P. The Expected Value (i.e., averages):Expected Value = m = Sum(Xi doOCo Pi), the sum is over all i's. Expected value is another name for the mean and (arithmetic) average.The...

This function calculates, in a "progressive" way, the mean and the standard deviation for a given vector (or matrix): it is useful in order to check stationarity of a random process looking at this two estimators.


Platforms: Matlab

it's useful to see how the mean and the standard deviation change when you use more samples to calculate it.

The stats toolbox provides a function to calculate the geometric mean of an array, but a function for the geometric standard deviation is oddly missing.Here is a function to fill that void, with no toolbox required.The function accepts a vector, matrix or N-D array; an optional flag to normalise...
