VoseStDev(Distribution Object)



Example model

Returns the standard deviation of a distribution object. The standard deviation is the positive square root of the variance, i.e. s = √V.

If a closed formula for the standard deviation exists, this is used.

For example, VoseStDev(VoseNormalObject(10,2)) will return the value 2 because the standard deviation of a normal distribution is equal to its second parameter .

Note that for each available distribution we have included a Distribution equations topic with the formulas for the mean, variance, skewness and kurtosis (if they exist): see for example Normal equations.
