R语言 binom.test()用法及代码示例

借助binom.test()方法，我们可以得到 R 编程中二项式分布假设的二项式检验。

用法： binom.test(x, n, p-value)

范例1：

# Using binom.test() method
  
gfg <- binom.test(58, 100)
  
print(gfg)

输出：

Exact binomial test

data: 58 and 100
number of successes = 58, number of trials = 100, p-value = 0.1332
alternative hypothesis:true probability of success is not equal to 0.5
95 percent confidence interval:
 0.4771192 0.6780145
sample estimates:
probability of success 
                  0.58 

范例2：

# Using binom.test() method
  
gfg <- binom.test(1, 36, 0.6)
  
print(gfg)

输出：

Exact binomial test

data: 1 and 36
number of successes = 1, number of trials = 36, p-value = 2.597e-13
alternative hypothesis:true probability of success is not equal to 0.6
95 percent confidence interval:
 0.0007030252 0.1452892647
sample estimates:
probability of success 
            0.02777778
