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

auto stan::math::log1m ( const var_value< T > &  a )

inline

The log (1 - x) function for variables.

The derivative is given by

\(\frac{d}{dx} \log (1 - x) = -\frac{1}{1 - x}\).

Template Parameters

T	Arithmetic or a type inheriting from EigenBase.

Parameters
