在 R 编程中计算对数正态概率密度 – dlnorm()函数
R语言中的dlnorm()
函数用于计算概率密度函数的对数正态值。它还创建了对数正态密度图。
Syntax: dlnorm(vec)
Parameters:
vec: x-values for normal density
示例 1:
# R program to compute
# log normal probability density
# Creating x-values for density
x <- seq(1, 10, by = 1)
# Calling dlnorm() function
y <- dlnorm(x)
y
输出:
[1] 0.398942280 0.156874019 0.072728256 0.038153457 0.021850715 0.013354538
[7] 0.008581626 0.005739296 0.003965747 0.002815902
示例 2:
# R program to compute
# log normal probability density
# Creating x-values for density
x <- seq(1, 10, by = 0.1)
# Calling dlnorm() function
y <- dlnorm(x)
# Plot a graph
plot(y)
输出:
