Generate the marginal likelihood of the following model structure:
$$x \sim Gaussian(A z + b, Sigma)$$
$$z \sim Gaussian(m,S)$$
Where Sigma is known. A is a \(dimx x dimz\) matrix, x is a \(dimx x 1\) random vector, z is a \(dimz x 1\) random vector, b is a \(dimm x 1\) vector. Gaussian() is the Gaussian distribution. See ?dGaussian
for the definition of Gaussian distribution.
The model structure and prior parameters are stored in a "LinearGaussianGaussian" object.
Marginal likelihood = p(x|m,S,Sigma)
# S3 method for LinearGaussianGaussian
marginalLikelihood_bySufficientStatistics(obj, ss, LOG = TRUE, ...)
A "LinearGaussianGaussian" object.
Sufficient statistics of x. In Gaussian-Gaussian case the sufficient statistic of sample x is a object of type "ssGaussianMean", it can be generated by the function sufficientStatistics().
Return the log density if set to "TRUE".
Additional arguments to be passed to other inherited types.
