R语言 计算累积Logistic密度 – plogis()函数
R语言中的 plogis() 函数用于计算分布的Logistic累积密度。它还可以创建逻辑累积分布的密度图。
语法: plogis(vec)
参数:
vec: 密度的X值向量
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
[1] 0.2689414 0.2890505 0.3100255 0.3318122 0.3543437 0.3775407 0.4013123

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:
