Description: Write statistical models in R and fit them by 'MCMC' and
        optimisation on 'CPUs' and 'GPUs', using Google 'TensorFlow'.
        'greta' lets you write your own model like in 'BUGS', 'JAGS'
        and 'Stan', except that you write models right in R, it scales
        well to massive datasets, and it’s easy to extend and build on.
        See the website for more information, including tutorials,
        examples, package documentation, and the 'greta' forum. This
        work is discussed at Golding (2019) <doi:10.21105/joss.01601>.
