inv_logit() [8/8]

template<typename T , require_eigen_vt< is_var, T > * = nullptr>

auto stan::math::inv_logit ( T &&  x )

inline

The inverse logit function for Eigen expressions with var value type.

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	type of Eigen expression

Parameters

x	Eigen expression

Returns

Inverse logit of argument.
