使用`proportionBF`进行单样本比例检验(两级以上)
using `proportionBF` to carry out one-sample proportion test (more than two levels)
我想为原假设为-
的单样本比例检验计算贝叶斯因子
The proportions for the levels for the nominal variable are not
different from the theoretical proportions
我知道如何使用 BayesFactor
包中的 proportionBF
在存在两个比例时执行此操作,零假设是两个级别的可能性相同 (p = 0.5
)。这相当于 stats::binom.test
.
# frequentist test (p-value > 0.05)
broom::tidy(stats::binom.test(x = 21, n = 44, p = 0.5))
#> # A tibble: 1 x 8
#> estimate statistic p.value parameter conf.low conf.high method
#> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <chr>
#> 1 0.477 21 0.880 44 0.325 0.633 Exact~
#> # ... with 1 more variable: alternative <chr>
# quantifying evidence in favor of null hypothesis
library(BayesFactor)
1/ proportionBF(y = 21, N = 44, p = 0.5, rscale = 0.707)
#> Bayes factor analysis
#> --------------
#> [1] Null, p=0.5 : 3.724132 ±0.02%
#>
#> Against denominator:
#> Alternative, p0 = 0.5, r = 0.707, p =/= p0
#> ---
#> Bayes factor type: BFproportion, logistic
但是我不知道当有两个以上的比例时如何做这个分析,相当于stats::chisq.test
(拟合优度检验)。
# frequentist test (p-value > 0.05)
table(mtcars$cyl)
#>
#> 4 6 8
#> 11 7 14
broom::tidy(stats::chisq.test(x = table(mtcars$cyl)))
#> # A tibble: 1 x 4
#> statistic p.value parameter method
#> <dbl> <dbl> <dbl> <chr>
#> 1 2.31 0.315 2 Chi-squared test for given probabilities
如何使用 BayesFactor
包计算此测试的贝叶斯因子?
(P.S。如果不可能,我也有兴趣了解任何其他可以做同样事情的包。)
