Is it better to use Metropolis algorithm rather than Accept-Reject algorithm in generating a random sample with Student's t distribution?
Homework Answers
- If we use one dimensional student t distribution , then the answer is No. We don't use Metropolis algorithm in one dimensional distribution, since Metropolis algorithm has autocorrelation problem. This problem can avoided in one dimensional distribution by using Accept Rejection algorithm..
- But if we have a multidimensional student t distribution then we use Metropolis algorithm to generate a random sample.

A random sample of 16 values is drawn from a mound-shaped and symmetric distribution. The sample mean is 15 and the sample standard deviation is 2. Use a level of significance of 0.05 to conduct a two-tailed test of the claim that the population mean is 14.5. (a) Is it appropriate to use a Student's t distribution? Explain. Yes, because the x distribution is mound-shaped and symmetric and σ is unknown.No, the x distribution is skewed left. No, the x distribution...
