该文通过用蒙特卡罗模拟法对几种能力估计方法进行比较研究,得出了CAT能力估计方法的较好设计方案.蒙特卡罗模拟结果表明,能力估计精度依赖于能力探查阶段和精确估计阶段的估计方法.
A better paradigm to estimate competency in CAT is proposed after comparing several estimating methods using Monte Carlo simulation. The results of Monte Carlo study show that the improvement of estimating accuracy is obtained provided different and effective estimating method being adopted in the rough and accurate estimating stages.
