英文摘要:
We test three common information criteria (IC) for selecting the order of a Hawkes process with an intensity kernel that can be expressed as a mixture of exponential terms. These processes find application in high-frequency financial data modelling. The information criteria are Akaike\'s information criterion (AIC), the Bayesian information criterion (BIC) and the Hannan-Quinn criterion (HQ). Since we work with simulated data, we are able to measure the performance of model selection by the success rate of the IC in selecting the model that was used to generate the data. In particular, we are interested in the relation between correct model selection and underlying sample size. The analysis includes realistic sample sizes and parameter sets from recent literature where parameters were estimated using empirical financial intra-day data. We compare our results to theoretical predictions and similar empirical findings on the asymptotic distribution of model selection for consistent and inconsistent IC.

中文摘要:
我们测试了三个公共信息准则(IC)来选择具有强度核的Hawkes过程的阶数,强度核可以表示为指数项的混合。这些过程可应用于高频金融数据建模。信息标准是Akaike的信息标准(AIC)、贝叶斯信息标准(BIC)和Hannan Quinn标准(HQ)。由于我们使用模拟数据,我们能够通过IC选择用于生成数据的模型的成功率来衡量模型选择的性能。特别是,我们对正确的模型选择和潜在样本量之间的关系感兴趣。该分析包括现实的样本量和最近文献中的参数集,其中参数是使用经验金融日内数据估计的。我们将我们的结果与一致和不一致IC模型选择的渐近分布的理论预测和类似经验结果进行了比较。
