在 R 编程中计算随机绘制的负二项式密度 – rnbinom()函数

R 语言中的rnbinom()函数用于计算负二项分布的随机密度。

示例 1:

Python3
# R program to compute random
# Negative Binomial Density
 
# Setting seed for
# random number generation
set.seed(1000)
 
# Set sample size
N <- 20
 
# Calling rnbinom() Function
y <- rnbinom(N, size = 10, prob = 0.5)
y


Python3
# R program to compute random
# Negative Binomial Density
 
# Setting seed for
# random number generation
set.seed(1000)
 
# Set sample size
N <- 100
 
# Calling rnbinom() Function
y <- rnbinom(N, size = 50, prob = 0.5)
 
# Plot a graph
plot(y)


输出:

[1]  9 12  8  4 10  3  9 19  3 14 11 11  6 15 14 12  6  5  5  4
