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'
.
