在评估季节性的相对风险时,空值是一个边界值。在这种情况下,存在零假设检验,但置信区间的标准方法并不适用。给出了一种在圆正态模型下构造置信区间的方法。无论模型假设和样本大小如何,如果模型正确,则建议的置信区间对基础季节性风险的所有值以及季节性风险的零边界值都有效。我们将我们的方法应用于最近报告中的季节性自杀数据。
In evaluating the relative risk of seasonality, the null value is a boundary value. In this case, tests for the null hypothesis exist, but standard methods for confidence intervals are not appropriate. We provide a method for constructing confidence intervals under the circular normal model. The proposed confidence intervals are valid for all values of the underlying seasonal risk if the model is correct and for the null boundary value of the seasonal risk, regardless of model assumptions and sample size. We apply our method to seasonal suicide data from a recent report.
