How can i calculate explained variance?

Thank you for very nice package
I want to calculate variance for each component
How can i calculate it?

Here, since the model is not Gaussian, nor based on Euclidean distance ($\ell_2$ norm) minimization, computing the explained variance is not suitable in this context.

Instead, we can compute a percentage of cumulative explained deviance, as introduced in section 2.1 of the related publication (link to access the preprint).

I think that this information is given in the output of the main function.
