WebNov 28, 2015 · A very common thing to do with a probability distribution is to sample from it. In other words, we want to randomly generate numbers (i.e. x values) such that the values of x are in proportion to the PDF. So for the standard normal distribution, N ∼ ( 0, 1) (the red curve in the picture above), most of the values would fall close to somewhere ... WebTo generate a sample of size 100 from a standard normal distribution (with mean 0 and standard deviation 1) we use the rnorm function. We only have to supply the n (sample size) argument since mean 0 and standard deviation 1 are the default values for the mean and stdev arguments. norm <- rnorm(100) Now let’s look at the first 10 observations.
