| <div class="block">The shape parameter to control the amount of robustness. Must be &gt; 1.0. |
| At larger values of epsilon, the huber criterion becomes more similar to least squares |

| Default is 1.35 to get as much robustness as possible while retaining |
| 95% statistical efficiency for normally distributed data. It matches sklearn |
| HuberRegressor and is "M" from <a href="http://statweb.stanford.edu/~owen/reports/hhu.pdf"> |
