Description

Is there implemented in tfp Normal-Inverse-Gamma distribution? I couldn't find it. If no, are there any plans to add this distribution?
https://en.wikipedia.org/wiki/Normal-inverse-gamma_distribution
I ask because I would like to test evidential deep learning in tf:

Research direction

Start by checking TensorFlow Probability's distribution catalog and documentation to determine whether a Normal-Inverse-Gamma distribution already exists. If it does not, clarify the expected API, mathematical behavior, tests, and documentation needed before implementation; completion would require an agreed design and verified distribution support.
