    While debugging the previous problem, I saw that the GaussianProductOp.ProductAverageConditional call returned the following distribution: {Gaussian(m/v=-0.4824, 1/v=0)}. How can this even be possible? How can "MeanTimesPrecision" be positive while "Precision" equals 0?

    Improper Gaussians are presented this way. If both mean-times-precision and precision were zero, the Gaussian would be printed out as Uniform.

    Tom gives a good explanation of improper distributions in this lecture somewhere between 0h34m and 0h42m.
