[SPARK-2850] [SPARK-2626] [mllib] MLlib stats examples + small fixes
Added examples for statistical summarization: * Scala: StatisticalSummary.scala ** Tests: correlation, MultivariateOnlineSummarizer * python: statistical_summary.py ** Tests: correlation (since MultivariateOnlineSummarizer has no Python API) Added examples for random and sampled RDDs: * Scala: RandomAndSampledRDDs.scala * python: random_and_sampled_rdds.py * Both test: ** RandomRDDGenerators.normalRDD, normalVectorRDD ** RDD.sample, takeSample, sampleByKey Added sc.stop() to all examples. CorrelationSuite.scala * Added 1 test for RDDs with only 1 value RowMatrix.scala * numCols(): Added check for numRows = 0, with error message. * computeCovariance(): Added check for numRows <= 1, with error message. Python SparseVector (pyspark/mllib/linalg.py) * Added toDense() function python/run-tests script * Added stat.py (doc test) CC: mengxr dorx Main changes were examples to show usage across APIs. Author: Joseph K. Bradley <joseph.kurata.bradley@gmail.com> Closes #1878 from jkbradley/mllib-stats-api-check and squashes the following commits: ea5c047 [Joseph K. Bradley] Merge remote-tracking branch 'upstream/master' into mllib-stats-api-check dafebe2 [Joseph K.

Bradley] Merge remote-tracking branch 'upstream/master' into mllib-stats-api-check 60c72d9 [Joseph K. Bradley] Fixed stat.py doc test to work for Python versions printing nan or NaN. b20d90a [Joseph K. Bradley] Merge remote-tracking branch 'upstream/master' into mllib-stats-api-check 4e5d15e [Joseph K. Bradley] Changed pyspark/mllib/stat.py doc tests to use NaN instead of nan. 32173b7 [Joseph K. Bradley] Stats examples update. c8c20dc [Joseph K. Bradley] Merge remote-tracking branch 'upstream/master' into mllib-stats-api-check cf70b07 [Joseph K.

Renamed statistical_summary.py to correlations.py ab48f6e [Joseph K. Bradley] RowMatrix.scala * numCols(): Added check for numRows = 0, with error message. * computeCovariance(): Added check for numRows <= 1, with error message. 65e4ebc [Joseph K.
