lub_constrain() [5/22]

template<typename T , typename L , typename U , require_all_stan_scalar_t< T, L, U > * = nullptr, require_not_var_t< return_type_t< T, L, U > > * = nullptr>

auto stan::math::lub_constrain ( T &&  x, L &&  lb, U &&  ub  )

inline

Return the lower and upper-bounded scalar derived by transforming the specified free scalar given the specified lower and upper bounds.

The transform is the transformed and scaled inverse logit,

\(f(x) = L + (U - L) \mbox{logit}^{-1}(x)\)

Template Parameters

T	Scalar.
L	Scalar.
U	Scalar.

Parameters

[in]	x	Free scalar to transform.
[in]	lb	Lower bound.
[in]	ub	Upper bound.

Returns

Lower- and upper-bounded scalar derived from transforming the free scalar.

Exceptions

std::domain_error

if ub <= lb
