Figure 1.
The bubble chart has three panels labelled C C I, E S I, and S S I. The x-axis is Matching ratio, with 1 to 1 and 1 to 2. The y-axis is A T E C O code number of digits, with values 2 and 3. Bubble size represents tau, with reference values 0.2, 0.4, 0.6, and 0.8. Point categories are p less than 0.01, p less than 0.05, p less than 0.1, and p greater than or equal to 0.1. In C C I, points appear at 1 to 1 and 1 to 2 for digit counts 2 and 3. In E S I, points appear at 1 to 1 for digit counts 2 and 3, and at 1 to 2 for digit counts 2 and 3. In S S I, points appear at 1 to 1 and 1 to 2 for digit counts 2 and 3.τ estimates by matching specifications
