# Gaussian.Uniform()

• ### Question

• Hi,

Can anyone help me in understanding "Gaussian.Uniform()" ? Is this something related to uniform distribution also?

• In Infer.NET terms, that's a Gaussian with a zero precision.

• It's an improper distribution - i.e. you the probability density for any real value is 0.0. It is useful in the calculus of message passing which involves products and ratios of distribution functions. Multiplying a Gaussian message by a uniform Gaussian message does not change the original message.
