Definition

The Tarone-Ware test is the generalization of the Mantel-Haenszel Test. $T = \frac{i = 1 \sum k w _{i} ( a _{i} - E ( a _{i} ))}{i = 1 \sum k Var ( a _{i} )} \to D N (0, 1)$ where $w_{i}$ is the weight for each table.

If $w_{i} = 1$ , then it is MH Statistic, if $w_{i} = n_{i}$ then it is Gehan statistic, and if $w_{i} = n_{i}$ then it is Tarone-Ware statistic.
