无意中，论文使用了错误的数据集。正确的数据集只包含536名学生的项目回答，而不是2144名学生，论文中使用的数据实际上是正确数据集的四倍。此外，计算机软件已得到改进，据信，下面获得的估计数是从更准确的吉布斯抽样中得出的。虽然正确数据集的点估计值（和估计的后验均值）大部分与以前发现的相似，但后验标准差的估计值大于以前报告的值
Inadvertently, an incorrect data set was used for the paper. The correct data set contains only the item responses of 536 students, as opposed to 2144, and the data that were used in the paper were actually a quadrupled copy of the correct data set. Also, the computer software has since been improved, and it is believed that the estimates that were obtained below are derived from a more accurate implementation of Gibbs sampling. Although the point estimates (and estimated posterior means) from the correct data set are for the most part similar to those found previously, the estimates of the posterior standard deviations are larger than previously reported
