logpdf_lazy_student_t


function logpdf_lazy_student_t(x:Expression<Real>, k:Expression<Real>) -> Expression<Real>

Observe a Student's t variate.

  • x: The variate.
  • k: Degrees of freedom.

Returns: the log probability density.

function logpdf_lazy_student_t(x:Expression<Real>, k:Expression<Real>, μ:Expression<Real>, σ2:Expression<Real>) -> Expression<Real>

Observe a Student's t variate with location and scale.

  • x: The variate.
  • k: Degrees of freedom.
  • μ: Location.
  • σ2: Squared scale.

Returns: the log probability density.
