1000 transitions using 10 leapfrog steps per transition would take 0.21 seconds.

<p>The rest of the output describes the progression of the algorithm.
An adaptation phase finds a good value for the step size scaling
parameter <code>eta</code>. The evidence lower bound (ELBO) is the variational
objective function and is evaluated based on a Monte Carlo estimate.
The variational inference algorithm in Stan is stochastic, which makes
it challen
