Error while dealing with Gaussians RRS feed

  • Question

  • I have written an inference model which involves Gaussian random variables. The model compiles correctly, but while inferring, I get the following run-time exception:

    The distribution is improper (Gaussian(m/v=-1.159, 1/v=-0.1572)). Cannot compute expectations.

    How do I understand this exception? What can be the possible causes of this and what should be the approach to debug it?

    Please note that I am making profuse use of ProductOfGaussians operator which is low on quality band. I am displayed a warning regarding this while the model compiles. I have not been able to find a workaround for this warning because I cannot avoid the product of Gaussian variables in the model.
