Questions for R / RStudio (Fall 2023) / Question for Gibbi sampler problem
« on: December 11, 2023, 06:02:58 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)

According to the plot result, we may guess when k equal to which number will let the mse be small. However, is there any more useful way to determine ?

I know how to calculate the MSE of the Trimmed value. But how do we calculate with the k?
I have no clue for this question. Would you mind provide some help? Thanks a lot!

Thank you for previous question suggestion. I meet another question for Q2 iii) similar with the Question 1, I found, if we initiate the theta.st <- NULL and theta.an <- NULL. The ide will returan error for in var(theta.an) : 'x' is NULL. In order solve this question, could we able to use the numeric?

The question requires us to evaluate the MC approximation by using the similar code in question 1. Therefore, I modify the x generate from Inverse cdf and pass the result into g(x). And the following steps are same with the Question1. However, my result is generate the NaN. I did not what's happened. Thank you so much!

Questions for R / RStudio (Fall 2023) / Question for HW6 Plot Picture
« on: October 20, 2023, 06:47:53 pm »
I just finished the HW6 Q3. The picture of the plot seems so strange. It does not like we discuss in the class. Is it caused by we consider the any numbers (z > 0 and z < 0)? Thank you!
