Wrapper function around the laplace_marginal function for a negative binomial likelihood.
Uses the 2nd parameterization. Returns the marginal density p(y|phi) by marginalizing out the latent gaussian variable, with a Laplace approximation. See the laplace_marginal function for more details.
Eta | The type of parameter arguments for the likelihood function. |
ThetaVec | A type inheriting from Eigen::EigenBase with dynamic sized rows and 1 column. |
Mean | type of the mean of the latent normal distribution |
CovarFun | A functor with an operator()(CovarArgsElements..., {TrainTupleElements...| PredTupleElements...}) method. The operator() method should accept as arguments the inner elements of CovarArgs . The return type of the operator() method should be a type inheriting from Eigen::EigenBase with dynamic sized rows and columns. |
CovarArgs | A tuple of types to passed as the first arguments of CovarFun::operator() |
[in] | y | observations. |
[in] | n_per_group | number of samples per group |
[in] | counts_per_group | total counts per group |
[in] | eta | non-marginalized model parameters for the likelihood. |
[in] | mean | the mean of the latent normal variable |
[in] | covariance_function | a function which returns the prior covariance. |
[in] | covar_args | arguments for the covariance function. |
[in] | theta_0 | the initial guess for the Laplace approximation. |
[in] | tolerance | controls the convergence criterion when finding the mode in the Laplace approximation. |
[in] | max_num_steps | maximum number of steps before the Newton solver breaks and returns an error. |
[in] | hessian_block_size | Block size of Hessian of log likelihood w.r.t latent Gaussian variable theta. |
[in] | solver | Type of Newton solver. Each corresponds to a distinct choice of B matrix (i.e. application SWM formula): 1. computes square-root of negative Hessian. 2. computes square-root of covariance matrix. 3. computes no square-root and uses LU decomposition. |
[in] | max_steps_line_search | Number of steps after which the algorithm gives up on doing a line search. If 0, no linesearch. |
[in,out] | msgs | stream for messages from likelihood and covariance |
