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