dmig_laplacian {mig} | R Documentation |
Laplacian of the MIG density with respect to the data
Description
Computes the sum of second derivatives of the multivariate
inverse Gaussian density with respect to the data argument
x
. The function is vectorized for more efficiency.
Usage
dmig_laplacian(x, xi, Omega, beta, scale = TRUE)
Arguments
x |
n by d matrix of quantiles
|
xi |
d vector of location parameters \boldsymbol{\xi} , giving the expected value
|
Omega |
d by d positive definite scale matrix \boldsymbol{\Omega}
|
beta |
d vector \boldsymbol{\beta} defining the half-space through \boldsymbol{\beta}^{\top}\boldsymbol{\xi}>0
|
Value
an n
vector
