Weba. To create a matrix with a dimension [10000 by 50] by sampling from X, we can use the rnorm function in R, which generates random numbers from a normal distribution. The mean and variance of the distribution are set to 2 and 1, respectively, using the arguments mean and sd (standard deviation), which is the square root of the variance. We can then use the … WebApr 6, 2024 · How to Create a Residual Plot in R.
