Stimulus response latency is the delay in the onset of stimulus-evoked neuronal activity. We develop maximum likelihood and least squares estimators of stimulus response latency and present a comparison of the performance of these methods with estimators commonly used in the neuroscience literature. The formal statistical change-point estimation problem is nontrivial due to the inclusion of a 'nuisance parameter', the end of stationarity in the stimulus-evoked activity. Our results suggest that the automation of the estimation of stimulus response latency will benefit from the use of the maximum likelihood estimator.
刺激反应潜伏期是刺激诱发神经元活动开始时的延迟。我们开发了刺激反应潜伏期的最大似然估计器和最小二乘估计器,并将这些方法的性能与神经科学文献中常用的估计器进行了比较。由于包含一个“干扰参数”,即刺激诱发活动中的平稳性结束,正式的统计变化点估计问题并不简单。我们的结果表明,刺激反应潜伏期估计的自动化将受益于最大似然估计器的使用。
