logL_GP | R Documentation |
Log-Likelihood function of a Gaussian Process
logL_GP(hp, db, mean, kern, post_cov, pen_diag)
hp |
A tibble, data frame or named vector containing hyper-parameters. |
db |
A tibble containing the values we want to compute the logL on. Required columns: Input, Output. Additional covariate columns are allowed. |
mean |
A vector, specifying the mean of the GP at the reference inputs. |
kern |
A kernel function. |
post_cov |
(optional) A matrix, corresponding to covariance parameter of the hyper-posterior. Used to compute the hyper-prior distribution of a new individual in Magma. |
pen_diag |
A jitter term that is added to the covariance matrix to avoid numerical issues when inverting, in cases of nearly singular matrices. |
A number, corresponding to the value of Gaussian log-Likelihood (where the covariance can be the sum of the individual and the hyper-posterior's mean process covariances).
