deriv_prior | R Documentation |
A collection of gradient for common priors.
deriv_prior(B, priorArgs, hessMethod)
B |
"matrix". The paramter that need to be added with a prior. The gradient and hessian are calculated conditional on B. B should be always an one-column matrix, |
priorArgs |
"list". priorArgs$prior_type: when prior_type is set to "mvnorm", you have to provide priorArgs$mean: "matrix", the mean of parameter, mu0 should be always an one-column matrix; priorArgs$covariance: "matrix", the covariance matrix. A g-prior can be constructed by setting it to X'X, where X is the covariates matrix.; priorArgs$shrinkage: "numeric", the shrinkage for the covariance. |
The parameters after "..." should be matched exactly.
"list". The gradient and hessian matrix, see below.
