Package org.apache.datasketches.theta

package org.apache.datasketches.theta

The theta package contains the basic sketch classes that are members of the Theta-Sketch Framework.

There is a separate /tuple/ package for many of the sketches that are derived from the same algorithms defined in the Theta-Sketch Framework paper.
