Dear R community! I would like to simulate distributions based on a polynomial model. It consists of 96 values and I want to randomly select new normaly distributed values around the modeled values. Furthermore, each value should be correlated with the previous one. Is it correct to therefore use mvrnorm? How do I define sigma? Thank you very much for your help.
