function

`scipy.stats._probability_distribution:_ProbabilityDistribution.mean`

source: /scipy/stats/_probability_distribution.py :339

Signature

def mean ( self , * , method )

Summary

Mean (raw first moment about the origin)

Parameters

method : {None, 'formula', 'transform', 'quadrature', 'cache'}: Method used to calculate the raw first 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 variance:

X.mean()
X.mean() == X.moment(order=1, kind='raw') == X.mu
