卡方输出作为向量
Output of chi-square as vector
我使用 chisq.test()
的卡方拟合优度检验。有没有办法将此函数的输出保存为向量,例如:
test <- c(X-squared, df, p-value)
?
chisq.test
的输出是一个列表
x <- c(A = 20, B = 15, C = 25)
test_chi <- chisq.test(x)
str(test_chi)
List of 9
$ statistic: Named num 2.5
..- attr(*, "names")= chr "X-squared"
$ parameter: Named num 2
..- attr(*, "names")= chr "df"
$ p.value : num 0.287
$ method : chr "Chi-squared test for given probabilities"
$ data.name: chr "x"
$ observed : Named num [1:3] 20 15 25
..- attr(*, "names")= chr [1:3] "A" "B" "C"
$ expected : Named num [1:3] 20 20 20
..- attr(*, "names")= chr [1:3] "A" "B" "C"
$ residuals: Named num [1:3] 0 -1.12 1.12
..- attr(*, "names")= chr [1:3] "A" "B" "C"
$ stdres : Named num [1:3] 0 -1.37 1.37
..- attr(*, "names")= chr [1:3] "A" "B" "C"
- attr(*, "class")= chr "htest"
我们可以用列表的一些元素创建一个向量
out <- c(test_chi$statistic,test_chi$parameter,test_chi$p.value)
out
X-squared df
2.5000000 2.0000000 0.2865048
另一种选择是使用库 broom
broom::tidy(test_chi)
# A tibble: 1 x 4
statistic p.value parameter method
<dbl> <dbl> <dbl> <chr>
1 2.5 0.287 2 Chi-squared test for given probabilities
