R语言计算Weibull累积密度的值 – pweibull()函数

R语言中的 pweibull() 函数用于计算Weibull分布的累积分布函数的值。它还为累积Weibull函数绘制了一个密度图。

语法： pweibull(x, shape)

参数：

x：数字向量

shape： 形状参数

例1 :

# R Program to compute
# Cumulative Weibull Density
  
# Creating a sequence of x-values
x <- seq(-5, 15, by = 1)
  
# Calling pweibull() Function
y <- pweibull(x, shape = 0.2)
y

输出

 [1] 0.0000000 0.0000000 0.0000000 0.0000000 0.0000000 0.0000000 0.6321206

# Creating a sequence of x-values
x <- seq(-5, 15, by = 0.2)
  
# Calling pweibull() Function
y <- pweibull(x, shape = 0.5)
  
# Plot a graph
plot(y)
