             Summary: Additional fixes to Mllib 2.0 documentation
                 Key: SPARK-16485
                 URL: https://issues.apache.org/jira/browse/SPARK-16485
             Project: Spark
          Issue Type: Sub-task
            Reporter: Timothy Hunter


While reviewing the documentation of MLlib, I found some additional issues.

Important issues that affect the binary signatures:
 - GBTClassificationModel: all the setters should be overriden
 - LogisticRegressionModel: setThreshold(s)
 - RandomForestClassificationModel: all the setters should be overriden
 - org.apache.spark.ml.stat.distribution.MultivariateGaussian is exposed but 
most of the methods are private[ml] -> do we need to expose this class for now?
- GeneralizedLinearRegressionModel: linkObj, familyObj, familyAndLink should 
not be exposed
- sqlDataTypes: name does not follow conventions. Do we need to expose it?

Issues that involve only documentation:
- Evaluator:
  1. inconsistent doc between evaluate and isLargerBetter
  2. missing `def evaluate(dataset: Dataset[_]): Double` from the doc (the 
other method with the same name shows up). This may be a bug in scaladoc.
- MinMaxScaler: math rendering
- GeneralizedLinearRegressionSummary: aic doc is incorrect


The reference documentation that was used was:
