仅从逻辑模型中提取p值重要的系数

Question

我已经运行了逻辑回归,我给它起了总结."得分"因此,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|)
(Intercept)        -4.188286233 1.94605597 -2.1521921 0.031382230 *

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

我所希望做到的,是让那些有变量的变量名和系数*,**或***挨着他们的Pr(>|z|)价值.换句话说,我希望上述变量和系数Pr(>|z|)<.05.

理想情况下,我想将它们放在数据框中.不幸的是,我尝试过以下代码不起作用.

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])
