Type Members

1.  case class BinarySample(isExperiment: Boolean, value: Double) extends Product with Serializable

   Class that represents the group and value of a sample.

   Class that represents the group and value of a sample.

   isExperiment

2.  class ChiSqTestResult extends TestResult[Int]

   Object containing the test results for the chi-squared hypothesis test.

3.  class KolmogorovSmirnovTestResult extends TestResult[Int]

   Object containing the test results for the Kolmogorov-Smirnov test.

   Object containing the test results for the Kolmogorov-Smirnov test.

4.  class StreamingTest extends Logging with Serializable

   Performs online 2-sample significance testing for a stream of (Boolean, Double) pairs.

   Performs online 2-sample significance testing for a stream of (Boolean, Double) pairs. The Boolean identifies which sample each observation comes from, and the Double is the numeric value of the observation.

   To address novelty affects, the peacePeriod specifies a set number of initial org.apache.spark.rdd.RDD batches of the DStream to be dropped from significance testing.

   The windowSize sets the number of batches each significance test is to be performed over. The window is sliding with a stride length of 1 batch. Setting windowSize to 0 will perform cumulative processing, using all batches seen so far.

   Different tests may be used for assessing statistical significance depending on assumptions satisfied by data. For more details, see StreamingTestMethod. The testMethod specifies which test will be used.

   Use a builder pattern to construct a streaming test in an application, for example:

   val model = new StreamingTest()
     .setPeacePeriod(10)
     .setWindowSize(0)
     .setTestMethod("welch")
     .registerStream(DStream)

5.  trait TestResult[DF] extends AnyRef

   Trait for hypothesis test results.
