摘要

作者研究了1984年7月至1993年12月期间，澳大利亚维多利亚州的太阳活动(太阳黑子数量)与96050例精神病入院之间的关系。Pearson相关系数计算结果为0.399 (P值;0.0001)。然而，这个值可能是两个序列中自相关的产物，而不是它们之间的关系，因为Pearson相关性不能解释数据的序列性质。为了克服这个问题，作者计算了序列之间的预白化交叉相关，并测试了它们是否不相关。检验结果显著(P值;0.006)，这为太阳黑子数量和精神病入院之间的关系提供了强有力的证据。

Is there a relationship between sunspot numbers and psychiatric admissions?

The authors examined the correlation between solar activity (sunspot numbers) and 96050 psychiatric admissions between July 1984 and December 1993, Victoria, Australia. Calculation of the Pearson correlation coefficient gave a value of 0.399 (P value; 0.0001). This value however, may be an artefact of autocorrelations within the two series rather than a relationship between them as the Pearson correlation does not account for the serial nature of the data. To overcome this problem the authors calculated the prewhitened cross-correlation between the series and tested whether they were uncorrelated. The test was significant (P value; 0.006), which gives strong evidence for a relationship between sunspot number and psychiatric admissions.
