plain_type_t< Mat > stan::math::stochastic_column_constrain	(	const Mat &	y,
		value_type_t< Mat > &	lp
	)

inline

Return a column stochastic matrix 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

Mat	type of the Matrix

Parameters

y	Free Matrix input of dimensionality (K - 1, M)
lp	Log probability reference to increment.
