%description
Compute the coefficient of determination for outcomes in n-dimensions. May
be useful for multidimensional predictions (such as a multinomial model)
or calculating goodness of fit from latent variable models such as
probabilistic topic models like latent Dirichlet allocation or
deterministic topic models like latent semantic analysis. Based on Jones
(2019) <arXiv:1911.11061>.
