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。
Syntax: rnbinom(N, size, prob)
Parameters:
N: Sample Size
size: Number of trials
prob: Probability
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
