3 Facts About Exponential Family

Thenas expected.
The derivation is a simple variational calculation using Lagrange multipliers. As a consequence, there exists a uniformly most powerful test for testing the hypothesis H0: θ ≥ θ0 vs.

is a normalization constant that is automatically determined by the remaining functions and serves to ensure that the given function is a probability density function (i.
If η(θ)=θ, then the exponential family is said to be in canonical read this post here If F is absolutely continuous with a density
