# Package org.apache.datasketches.pig.theta

Pig UDFs for Theta sketch.

See: Description

Class Summary
AexcludeB: This is a Pig UDF that performs the A-NOT-B Set Operation on two given Sketches.
DataToSketch: This is a Pig UDF that builds Sketches from data.
DataToSketch.Initial: Class used to calculate the initial pass of an Algebraic sketch operation.
DataToSketch.IntermediateFinal: Class used to calculate the intermediate or final combiner pass of an Algebraic sketch operation.
ErrorBounds: This is a User Defined Function (UDF) for returning the Double value result along with a lower and upper bound.
Estimate: Returns the unique count estimate of a sketch as a Double.
Intersect: This is a Pig UDF that performs the Intersection Set Operation on Sketches.
Intersect.Initial: Class used to calculate the initial pass of an Algebraic sketch operation.
Intersect.IntermediateFinal: Class used to calculate the intermediate or final combiner pass of an Algebraic intersection operation.
JaccardSimilarity: This is a Pig UDF that performs the JaccardSimilarity Operation on two given Sketches.
SketchToString: This is a User Defined Function (UDF) for "pretty printing" the summary of a sketch from a Sketch Tuple.
Union: This is a Pig UDF that performs the Union Set Operation on Sketches.
Union.Initial: Class used to calculate the initial pass of an Algebraic sketch operation.
Union.IntermediateFinal: Class used to calculate the intermediate or final combiner pass of an Algebraic union operation.
