Simulating Gaussian Process in R w/ Mean & Variance

Click For Summary
SUMMARY

This discussion focuses on simulating a Gaussian stationary process in R using predefined mean and variance. The key method involves utilizing the R function rnorm(n, mean, standard_deviation) to generate a random vector of size n from a univariate normal distribution. The formula Y = σX + m is established, where σ represents the standard deviation and m the mean of the desired process. This approach effectively allows users to simulate their real-life processes accurately.

Hi everybody

Any ideas how to simulate a Gaussian stationary process in R language using predefined variance and mean?
I have a uni-variate normal distribution for my real life process
Thank you

Let X be the uivariate normal. Then Y=σX + m where σ is the standard deviation and m is the mean of the process (Y) that you want to simulate. (I don't know what R language is.)
 
Hey MarkJ.

In R, you should use output = rnorm(n,mean,standard_deviation) to simulate from a normal distribution with n observations given those probabilities (you will get a random vector of size n from this distribution).
