marginalLikelihood_bySufficientStatistics.LinearGaussianGaussian {bbricks}R Documentation

Marginal likelihood of a "LinearGaussianGaussian" object, using sufficient statistics


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 class '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.
