> The documentation for Linear Regression in Pyspark includes an example, which contains a TypeError:
> https://spark.apache.org/docs/latest/api/python/reference/api/pyspark.ml.regression.LinearRegression.html?highlight=linearregression#pyspark.ml.regression.LinearRegression
> {code}
> >>> abs(model.transform(test1).head().newPrediction - 1.0) < 0.001
> True
> >>> lr.setParams("vector")
> Traceback (most recent call last):
>     ...
> TypeError: Method setParams forces keyword arguments.
> {code}
> I'm pretty sure we don't intend this, and it can be resolved by just changing the function call to use keyword args.
