Abstract
The power of a test of Edwards to detect seasonality or cyclic variation in the rate of an epidemiological event is derived and tabulated. A simple harmonic or sinusoidal form of variation is assumed, but the power results should also apply approximately to other situations with similar types of rate oscillation. The results may be used by investigators to determine the sample size required in order to detect seasonal variation of a given magnitude, or conversely to calculate the probability of detecting seasonality of various amplitudes with a sample of fixed size.
摘要
推导并列表给出了爱德华兹检验检测流行病学事件发生率中的季节性或周期性变化的检验功效。假定变化形式为简单谐波或正弦形式，但检验功效结果也应大致适用于具有类似发生率振荡类型的其他情况。研究人员可使用这些结果来确定检测给定幅度季节性变化所需的样本量，或者反过来计算用固定大小的样本检测各种幅度季节性变化的概率。
