Original Docstring for Distribution

Construct a log-normal distribution.

The LogNormal distribution models positive-valued random variables whose logarithm is normally distributed with mean loc and standard deviation scale. It is constructed as the exponential transformation of a Normal distribution.

loc Floating-point Tensor; the means of the underlying Normal distribution(s).
scale Floating-point Tensor; the stddevs of the underlying Normal distribution(s).
validate_args Python bool, default False. Whether to validate input with asserts. If validate_args is False, and the inputs are invalid, correct behavior is not guaranteed.
allow_nan_stats Python bool, default True. If False, raise an exception if a statistic (e.g. mean/mode/etc...) is undefined for any batch member If True, batch members with valid parameters leading to undefined statistics will return NaN for this statistic.
name The name to give Ops created by the initializer.
