log_mix() [9/12]

template<typename T_theta , typename T_lambda1 , typename T_lambda2 , require_all_arithmetic_t< T_theta, T_lambda1, T_lambda2 > * = nullptr>

double stan::math::log_mix ( T_theta  theta, T_lambda1  lambda1, T_lambda2  lambda2  )

inline

Return the log mixture density with specified mixing proportion and log densities.

\[ \mbox{log\_mix}(\theta, \lambda_1, \lambda_2) = \log \left( \theta \lambda_1 + (1 - \theta) \lambda_2 \right). \]

Template Parameters

T_theta	type of mixing proportion - must be an arithmetic type
T_lambda1	type of first log density - must be an arithmetic type
T_lambda2	type of second log density - must be an arithmetic type

Parameters

[in]	theta	mixing proportion in [0, 1].
[in]	lambda1	first log density.
[in]	lambda2	second log density.

Returns

log mixture of densities in specified proportion
