scipy.stats.Uniform.

standard_deviation#

Uniform.standard_deviation(*, method=None)[source]#

Standard deviation (square root of the second central moment)

Parameters:
method{None, ‘formula’, ‘transform’, ‘normalize’, ‘quadrature’, ‘cache’}

Method used to calculate the central second moment. Not all methods are available for all distributions. See moment for details.

Examples

Instantiate a distribution with the desired parameters:

>>> from scipy import stats
>>> X = stats.Normal(mu=1., sigma=2.)

Evaluate the standard deviation:

>>> X.standard_deviation()
2.0
>>> X.standard_deviation() == X.moment(order=2, kind='central')**0.5 == X.sigma
True
