Webpython——利用scipy.stats import pearsonr计算皮尔逊相关系数. 因此,要先检验相关系数的显著性,如果显著,证明相关系数有统计学意义,下一步再来看相关系数大小,如果相关系数没有统计学意义,那意味着你研究求得的相关系数也许是抽样误差或者测量误差造成 ... WebFeb 27, 2024 · These functions would return a result object - which would no longer include any results, just configuration information - and the user would pass this object into the statistic function (e.g. `pearsonr`). In this case, it sounds like we would just be using these functions to create an object that specifies configuration information.
