生成人类视动和前庭眼球震颤的快相间隔直方图，并拟合到先前研究中使用的统计分布。分布不取决于刺激类型（视动或前庭）。逆高斯分布或伽玛分布比倒高斯分布更适合数据，但没有一个分布特别适合数据。然而，在某些情况下，这些分布的解释在生理学上比其他分布更令人满意。就首选模型类别以及支持特定模型所需的实验提出建议。我们的结果对先前研究的有效性提出了质疑，这些研究将统计分布拟合到与我们的规模相当的数据集。
Histograms of fast-phase intervals in human optokinetic and vestibular nystagmus were generated, and fitted to statistical distributions used in previous studies. The distributions did not depend on stimulation type (optokinetic or vestibular). An inverse Gaussian or a gamma distribution fitted the data better than did a reciprocal Gaussian distribution, but none fitted the data especially well. In some cases, however, the interpretation of these distributions is more physiologically satisfactory than in others. Recommendations are made on which class of models is preferred, and the experiments needed to support the particular models. Our results call into question the validity of previous studies that fit statistical distributions to data sets of a size comparable to ours.
