update_lazy_scaled_inverse_gamma_weibull


function update_lazy_scaled_inverse_gamma_weibull(x:Expression<Real>, k:Expression<Real>, a:Expression<Real>, α:Expression<Real>, β:Expression<Real>) -> (Expression<Real>, Expression<Real>)

Update the parameters of a scaled inverse-gamma distribution with a Weibull likelihood with known shape.

  • x: The variate.
  • k: Likelihood shape.
  • a: Constant scale.
  • α: Prior shape.
  • β: Prior scale.

Returns: the posterior hyperparameters α' and β'.
