bbricks 0.1.3 (2020-04-26)

Enhance documentations.

Improvements

bbricks 0.1.2 (2020-04-14)

Add features and enhance documentations. Fix minor bugs.

New features

New Model Structures: + Linear Gaussian system. + Gaussian and Gaussian conjugate structure. + Gaussian and Inverse-Wishart conjugate structure.

New Inference Tasks: + Sample from the posterior distribution. + Calculate density values from the posterior distribution.

New Distributions: + Inverse Gamma distribution. + Wishart and Inverse-Wishart distributions.

Bug fixes

Fixed bug: rGaussian returns “non-conformable arrays” error when sample mean “mu” is a 1 column matrix.

Improvements

Reformat all the function documentations, now they are more readable.
