simplex_constrain() [2/6]

template<typename Vec , require_eigen_vector_t< Vec > * = nullptr, require_not_st_var< Vec > * = nullptr>

plain_type_t< Vec > stan::math::simplex_constrain ( const Vec &  y, value_type_t< Vec > &  lp  )

inline

Return the simplex corresponding to the specified free vector and increment the specified log probability reference with the log absolute Jacobian determinant of the transform.

The simplex transform is defined through a centered stick-breaking process.

Template Parameters

Vec	type of the vector

Parameters

y	Free vector input of dimensionality K - 1.
lp	Log probability reference to increment.

Returns

Simplex of dimensionality K.
