| | | | | | | | | | | | | | | Python API for the KS-test Statistics.kolmogorovSmirnovTest(data, distName, *params) I'm not quite sure how to support the callable function since it is not serializable.

Known issue: unpickle array from Pyrolite is broken in Python 3, those tests are skipped. TODO: ec2/spark-ec2.py is not fully tested with python3.

* [SPARK-5477] refactor stat.pyXiangrui Meng2015-01-293-0/+340
There is only a single `stat.py` file for the `mllib.stat` package. We recently added `MultivariateGaussian` under `mllib.stat.distribution` in Scala/Java. It would be nice to refactor `stat.py` and make it easy to expand. Note that `ChiSqTestResult` is moved from `mllib.stat` to `mllib.stat.test`. The latter is used in Scala/Java. It is only used in the return value of `Statistics.chiSqTest`, so this should be an okay change. davies Author: Xiangrui Meng <meng@databricks.com> Closes #4266 from mengxr/py-stat-refactor and squashes the following commits: 1a5e1db [Xiangrui Meng] refactor stat.py
