tfd_variance: Variance.

Description

Variance is defined as, Var = E[(X - E[X])**2] where X is the random variable associated with this distribution, E denotes expectation, and Var$shape = batch_shape + event_shape.

Usage

tfd_variance(distribution, ...)

Value

a Tensor of shape sample_shape(x) + self$batch_shape with values of type self$dtype.

Arguments

distribution

The distribution being used.

...

Additional parameters passed to Python.
