inv_logit() [6/6]

template<typename T , require_stan_scalar_or_eigen_t< T > * = nullptr>

auto stan::math::inv_logit ( const var_value< T > &  a )

inline

The inverse logit function for variables (stan).

See inv_logit() for the double-based version.

The derivative of inverse logit is

\(\frac{d}{dx} \mbox{logit}^{-1}(x) = \mbox{logit}^{-1}(x) (1 - \mbox{logit}^{-1}(x))\).

Template Parameters

T	Arithmetic or a type inheriting from EigenBase.

Parameters

a	Argument variable.

Returns

Inverse logit of argument.
