计算 R 编程中的累积 Weibull 密度值 – 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。它还绘制了 Cumulative Weibull 函数的密度图。

Syntax: pweibull(x, shape)

Parameters:
x: Numeric Vector
shape: Shape Parameter

示例 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
 [8] 0.6829508 0.7122695 0.7327332 0.7483534 0.7609229 0.7713981 0.7803493
[15] 0.7881434 0.7950303 0.8011877 0.8067464 0.8118052 0.8164408 0.8207138

示例 2：
