Notes. U(xmin; xmax): uniform distribution between xmin and xmax. J(xmin; xmax): Jeffreys (log-flat) distribution between xmin and xmax. N(μ; σ): normal distribution with mean μ and standard deviation σ. tN(μ; σ; xmin; xmax): normal distribution with mean μ and standard deviation σ, truncated from xmin to xmax.
