R语言 计算Weibull密度值 – dweibull()函数

R语言中的 dweibull() 函数用于计算Weibull分布的不同数值的Weibull密度值。

语法： dweibull(x, shape)

参数：

x： 数值向量

shape： 形状参数

例1 :

# R Program to compute
# Weibull Density
  
# Creating a sequence of x-values
x <- seq(-10, 10, by = 1)
  
# Calling dweibull() Function
y <- dweibull(x, shape = 0.2)
y

输出
