# Function std
|
|
|
|
Compute the standard deviation of a list of values, defined as the square root of the variance: std(A) = sqrt(var(A)). In case of a (multi dimensional) array or matrix, the standard deviation over all elements will be calculated.
|
|
|
|
std(a, b, c, ...) std(A) std(A, normalization)
|
|
|
|
Where `normalization` is a string having one of the following values:

`array` | Array | Matrix | A single matrix or or multiple scalar values
|
|
`normalization` | String | Default value: 'unbiased' Determines how to normalize the standard deviation: - 'unbiased' (default) The sum of squared errors is divided by (n - 1) - 'uncorrected' The sum of squared errors is divided by n - 'biased' The sum of squared errors is divided by (n + 1)
