在 R 编程中计算累积逻辑密度 - plgis()函数
R 语言中的plogis()
函数用于计算分布的逻辑累积密度。它还创建了逻辑累积分布的密度图。
Syntax: plogis(vec)
Parameters:
vec: Vector of x-values for density
示例 1:
# R program to calculate
# cumulative logistic density
# Create a vector of x-values
x <- seq(-1, 1, by = 0.1)
# Calling the plogis() function
y <- plogis(x)
y
输出:

示例 2:
# R program to calculate
# cumulative logistic density
# Create a vector of x-values
x <- seq(-20, 20, by = 0.1)
# Calling the plogis() function
y <- plogis(x)
# Plot the graph
plot(y)
输出:
