@property<EOL><INDENT>def df(self):<DEDENT>
return self._df<EOL>
The degrees of freedom of the distribution.

        This controls the degrees of freedom of the distribution. The tails of the
        distribution get more heavier the smaller `df` is. As `df` goes to
        infinitiy, the distribution approaches the Multivariate Normal with the same
        `loc` and `scale`.

        Returns:
          The `df` `Tensor`.
