Statistical Distributions (contrib)

Classes representing statistical distributions and ops for working with them.

Classes for statistical distributions

Univariate (scalar) distributions

• tf.contrib.distributions.Binomial
• tf.contrib.distributions.Bernoulli
• tf.contrib.distributions.Beta
• tf.contrib.distributions.Categorical
• tf.contrib.distributions.Chi2
• tf.contrib.distributions.Chi2WithAbsDf
• tf.contrib.distributions.Exponential
• tf.contrib.distributions.Gamma
• tf.contrib.distributions.InverseGamma
• tf.contrib.distributions.Laplace
• tf.contrib.distributions.LaplaceWithSoftplusScale
• tf.contrib.distributions.Normal
• tf.contrib.distributions.NormalWithSoftplusScale
• tf.contrib.distributions.Poisson
• tf.contrib.distributions.StudentT

Multivariate distributions

Multivariate normal

Posterior inference with conjugate priors

Functions that transform conjugate prior/likelihood pairs to distributions representing the posterior or posterior predictive.

Normal likelihood with conjugate prior
