【问题描述】:
我正在尝试使用 r 从序数回归中获取我的优势比的 p 值。
我之前在这样的对数赔率上构建了我的 p 值
scm <- polr(finaloutcome ~ Size_no + Hegemony + Committee, data = data3, Hess = TRUE)
(ctable <- coef(summary(scm)))
计算并存储 p 值
p <- pnorm(abs(ctable[, "t value"]), lower.tail = FALSE) * 2
## combined table
(ctable <- cbind(ctable, "p value" = p))
我是通过这样的优势比创建的:
ci <- confint.default(scm)
exp(coef(scm))
## OR and CI
exp(cbind(OR = coef(scm), ci))
但是,我现在不确定如何为优势比创建 p 值。使用我得到的以前的方法:
(ctable1 <- exp(coef(scm)))
p1 <- pnorm(abs(ctable1[, "t value"]), lower.tail = FALSE) * 2
(ctable <- cbind(ctable, "p value" = p1))
但是我得到了错误:ctable1[, "t value"] 中的错误:维数不正确
优势比输出样本:

|---|---|---|
| 9.992240e-01 | 6.957805e-02 | 1.204437e-01 |

嗨!如果可能,请添加少量数据样本以更好地找到问题的答案。在您的情况下,这将有助于对允许适合 polr() 函数的样本数据进行采样,但仍会产生错误。

@JuanBosco 谢谢我添加了一些样本数据和优势比输出
