WebApr 4, 2024 · The rnorm () in R is a built-in function that generates a vector of normally distributed random numbers. It takes three arguments: n, mean, and sd, where n is the sample size, mean is the mean of the normal distribution, and sd is the standard deviation. Syntax rnorm (n, mean, sd) Parameters n: It is the number of observations (sample size). WebIn general, to make your sample mean and variance exactly equal to a pre-specified value, you can appropriately shift and scale the variable.
