贝叶斯建模的最新进展允许无似然后验估计。这样的估计技术是至关重要的模拟为基础的模型,其似然函数可能很难,甚至不可能得到的理解。然而,目前的方法是有限的,它们依赖于足够的统计和/或公差阈值。在这篇文章中,我们提供了一种新的方法,不需要汇总统计量,误差项或阈值,并且可以推广到所有可以模拟的心理学模型。我们使用我们的算法来适应各种认知模型与已知的似然函数,以确保我们的方法的准确性。然后,我们将我们的方法应用于两个现实世界的例子,以说明我们的方法解决的复杂问题的类型。在第一个例子中,我们拟合了信号检测的纠错准则模型,其准则在每次尝试后动态调整。然后,我们适合两个模型的选择响应时间的实验数据:线性弹道累加器模型,它有一个已知的可能性,泄漏竞争累加器模型的可能性是棘手的。这两个模型的估计后验分布允许通过传统的贝叶斯统计进行直接的参数解释和模型比较-这是以前不可能的壮举。
Recent advancements in Bayesian modeling have allowed for likelihood-free posterior estimation. Such estimation techniques are crucial to the understanding of simulation-based models, whose likelihood functions may be difficult or even impossible to derive. However, current approaches are limited by their dependence on sufficient statistics and/or tolerance thresholds. In this article, we provide a new approach that requires no summary statistics, error terms, or thresholds, and is generalizable to all models in psychology that can be simulated. We use our algorithm to fit a variety of cognitive models with known likelihood functions to ensure the accuracy of our approach. We then apply our method to two real-world examples to illustrate the types of complex problems our method solves. In the first example, we fit an error-correcting criterion model of signal detection, whose criterion dynamically adjusts after every trial. We then fit two models of choice response time to experimental data: the Linear Ballistic Accumulator model, which has a known likelihood, and the Leaky Competing Accumulator model whose likelihood is intractable. The estimated posterior distributions of the two models allow for direct parameter interpretation and model comparison by means of conventional Bayesian statistics – a feat that was not previously possible.
