This erratum corrects Tables 7 and 8 of our paper, “Quantal Response Equilibrium for Extensive Form Games,” which appeared in this journal, Vol. 1, No. 1, pp. 9–41 (1998). We have corrected the last column of numbers in each table, which are the estimated take probabilities for the 2-parameter model. There are two other minor changes. The estimated value of lambda for this model has also been corrected. (The likelihood values were reported correctly in the original.) Also, in the fifth row of the first column of Table 7, σ 2 has been corrected to γ . We are grateful to James Friedman and Claudio Mezzetti for discovering these errors and bringing them to our attention.
