logpdf_lazy_matrix_student_t


function logpdf_lazy_matrix_student_t(X:Expression<Real[_,_]>, k:Expression<Real>, M:Expression<Real[_,_]>, U:Expression<LLT>, V:Expression<LLT>) -> Expression<Real>

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

  • X: The variate.
  • k: Degrees of freedom.
  • M: Mean.
  • U: Among-row covariance.
  • V: Among-column covariance.

Returns: the log probability density.
