WebSep 27, 2024 · The Binomial test, sometimes referred to as the Binomial exact test, is a test used in sampling statistics to assess whether a proportion of a binary variable is equal to some hypothesized value. In this article, we explore the key features of this test and walk through an example test. What are the hypotheses of the binomial test? WebSep 6, 2024 · I want to use the negative binomial as a loss functions in Keras or Tensorflow on a feed forward neural network. To my knowledge, after looking through available loss functions, such a function doesn't exist for keras or tensorflow (although I'm hoping I'm wrong and I just missed something).
