Calculate the sufficient statistics for the mean and variance of x.

These sufficient statistics are computed using the one pass algorithm on an input that's optionally shifted. See:

x A Tensor.
axes Array of ints. Axes along which to compute mean and variance.
shift A Tensor containing the value by which to shift the data for numerical stability, or None if no shift is to be performed. A shift close to the true mean provides the most numerically stable results.
keepdims produce statistics with the same dimensionality as the input.
name Name used to scope the operations that compute the sufficient stats.

Four Tensor objects of the same type as x:

  • the count (number of elements to average over).
  • the (possibly shifted) sum of the elements in the array.
  • the (possibly shifted) sum of squares of the elements in the array.
  • the shift by which the mean must be corrected or None if shift is None.
