Chapter 9 - Markov Chain Monte Carlo
This week has been an informal introduction to Markov chain Monte Carlo (MCMC) estimation. The goal has been to introduce the purpose and approach MCMC algorithms. The major algorithms introduced were the Metropolis, Gibbs sampling, and Hamiltonian Monte Carlo algorithms. Each has its advantages and disadvantages. The ulam function in the rethinking package was introduced. It uses the Stan (mc-stan.org) Hamiltonian Monte Carlo engine to fit models as they are defined in this book. General advice about diagnosing poor MCMC fits was introduced by the use of a couple of pathological examples.
Place each answer inside the code chunk (grey box). The code chunks should contain a text response or a code that completes/answers the question or activity requested. Make sure to include plots if the question requests them.
Finally, upon completion, name your final output .html
file as: YourName_ANLY505-Year-Semester.html and publish
the assignment to your R Pubs account and submit the link to Canvas.
Each question is worth 5 points.
Questions
8-1. Re-estimate the terrain ruggedness model from the chapter, but now using a uniform prior for the standard deviation, sigma. The uniform prior should be dunif(0,1). Visualize the priors. Use ulam to estimate the posterior distribution of sigma. Visualize the posterior distribution of sigma for both models. Do not use a ‘pairs’ plot. Does the different prior have any detectable influence on the posterior distribution of sigma? Why or why not?

The individual model outputs are likewise relatively similar. Hence, no
detectable influence on the posterior distribution of sigma.
8-2. Modify the terrain ruggedness model again. This time, change the prior for b[cid] to dexp(0.3). Plot the joint posterior. Do not use a ‘pairs’ plot. What does this do to the posterior distribution? Can you explain it?

#From the plot we can see plot a should be a normal distribution as the
prior is aroung 0 and spread in between 2 and -2. Plot b is Cauchy
distribution which contains some extreme value go up to over 30 and
-50.
Compare the samples for the parameters a and b. Plot the trace plots. Can you explain the different trace plots? If you are unfamiliar with the Cauchy distribution, you should look it up. The key feature to attend to is that it has no expected value. Can you connect this fact to the trace plot?
8-5. Recall the divorce rate example from Chapter 5. Repeat that analysis, using ulam this time, fitting models m5.1, m5.2, and m5.3. Use compare to compare the models on the basis of WAIC or PSIS. To use WAIC or PSIS with ulam, you need add the argument log_log=TRUE. Explain the model comparison results.
