The Normal Distribution
- rnorm: random sampling from the normal distribution
- pnorm: cumulative density function of the normal distribution
The Normal Distribution: rnorm
rnorm(n, mean = 0, sd = 1)
The Normal Distribution: pnorm
pnorm(q, mean = 0, sd = 1, lower.tail = TRUE)
Important functionality: lower.tail
Empirical Cumulative Distribution Function (ECDF)
plot.ecdf(rnorm(100))
Empirical Cumulative Distribution Function (ECDF)
plot.ecdf(rnorm(1000), ylab = "ECDF(x)")
Plotting multiple ECDFs in the same graph
Hint: look through the examples on the function’s help page
