> The toString method of LogisticRegressionModel calls get method on an Option
> (threshold) without a safeguard. In spark-shell, the following code
> {code:title=lbfgs.scala|borderStyle=solid}
> val model = algorithm.run(data).clearThreshold()
> {code}
> in lbfgs code will fail as toString method will be called right after
> clearThreshold() to show the results in the REPL.
