r - 从逻辑模型中仅提取 p 值显着的系数

Question

我已经运行了一个逻辑回归，我命名的摘要。 “得分”相应地，summary(score)给我以下

Deviance Residuals: 
    Min       1Q   Median       3Q      Max  
-1.3616  -0.9806  -0.7876   1.2563   1.9246  

                       Estimate Std. Error    z value    Pr(>|z|)

Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1

(Dispersion parameter for binomial family taken to be 1)

    Null deviance: 757.25  on 572  degrees of freedom
Residual deviance: 725.66  on 565  degrees of freedom
AIC: 741.66

Number of Fisher Scoring iterations: 4

我希望实现的是获得具有 * 的那些变量的变量名称和系数。 , ** , 或 ***在他们旁边 Pr(>|z|)值(value)。换句话说，我想要前面提到的变量和系数 Pr(>|z|) < .05。

理想情况下，我想将它们放入数据框中。不幸的是，我尝试过的以下代码不起作用。

variable_try <-
  summary(score)$coefficients[if(summary(score)$coefficients[, 4] <= .05, 
                                 summary(score)$coefficients[, 1]),]

Error: unexpected ',' in "variable_try <-
summary(score)$coefficients[if(summary(score)$coefficients[,4] < .05,"

Answer 1

那这个呢:

data.frame(summary(score)$coef[summary(score)$coef[,4] <= .05, 4])
