Just like the two coefficients we’ve seen before, here too the output is on the range of [0,1].
Theil’s U, also referred to as the Uncertainty Coefficient, is based on the conditional entropy between x and y — or in human language, given the value of x, how many possible states does y have, and how often do they occur. Just like Cramer’s V, the output value is on the range of [0,1], with the same interpretations as b…
