Namespaces
namespace	stan
	The lgamma implementation in stan-math is based on either the reentrant safe lgamma_r implementation from C or the boost::math::lgamma implementation.
namespace	stan::math
	Matrices and templated mathematical functions.

Functions
template<typename T1 , typename T2 , require_all_arithmetic_t< T1, T2 > * = nullptr>
return_type_t< T1, T2 >	stan::math::log_falling_factorial (const T1 x, const T2 n)
	Return the natural log of the falling factorial of the specified arguments.
template<typename T1 , typename T2 , require_any_container_t< T1, T2 > * = nullptr>
auto	stan::math::log_falling_factorial (const T1 &a, const T2 &b)
	Enables the vectorized application of the log_falling_factorial function, when the first and/or second arguments are containers.
