\text {p-value}\leq 0.05\\ 就可以认为假设是不正确的。 0.05这个标准就是显著水平,当然选择多少作为显著水平也是主观的。 比如,上面的扔硬币的例子,如果取单侧P值,那么根据我们的计算,如果扔10次出现9次正面: \text {p-value}=P(9\leq X\leq 10)=0.01\leq 0.05\\ 表示出来如下图所示: 我们可以认为...

with a p-value of 0.0000 (lower than the 1% level). I would like to know whether the fact that the p-value is so low is a sign of a spurious modelisation or of a problem with data or of any other problem. Is that common to have p-value of 0.0000 in the cases of error correct...
# 创建一个线性模型 model <- lm(y ~ x, data = dataset) # 打印线性模型的摘要信息 summary(model) # 提取p值 p_value <- summary(model)$coefficients[, 4] print(p_value) 在上述代码中,我们首先使用lm()函数创建了一个线性模型,其中y是因变量,x是自变量,dataset是包含这两个变量的数据集。然后,...

Modified Poisson regression was used to ascertain factors associated with mortality at bivariable and multivariable levels. Associations were presented through adjusted prevalence ratios with their 95% confidence intervals. Data were analyzed using STATA v15. RESULTS. Of the 173 patients' medical records...
