R语言 计算随机抽取的Logistic密度 – rlogis()函数

R语言中的 rlogis() 函数是用来计算一系列输入中的随机Logistic密度。

语法： rlogis(N)

参数：

N： 样本大小

例子1 :

# R program to generate 
# random logistic density points
  
# Setting seed for
# random number generation
set.seed(1000)
  
# Set sample size
N <- 20
  
# Calling rlogis() Function
y <- rlogis(N)
y 

输出

 [1] -0.71779506  1.14636578 -2.05114837  0.80365206  0.06563317 -2.62196720
 [7]  1.03929969  0.33730220 -1.29048105 -1.06622107 -0.61931410  1.12795649
[13] -0.76720400  1.86443303  1.17562774 -2.54319669 -0.02953117  0.55442681
[19] -2.37810163  0.33889069

例2 :

# R program to generate

set.seed(1000)
  
# Set sample size
N <- 500
  
# Calling rlogis() Function
y <- rlogis(N)
  
# Plot a graph
plot(y)
