       Question for Gibbi sampler problem
       By: YuyangWu Date: December 11, 2023, 5:02 pm
       ---------------------------------------------------------
       When I review the final exam. I still feel confusing that why we
       set the X[1] <- rnorm(1,10,1) but in the practice exam, we set
       the X[1] <- rnorm(1)

       I think X1 and Y1 are the initial variables. In the lab, it was
       my understanding that we were sampling from a Normal
       Distribution with a mean of 10 and a standard deviation of 1 for
       the initial variables. However, in the practice exam, initial
       states were not specified. Consequently, we generated a single
       random variable from a normal distribution without explicitly
       stating the mean and sd.
