This question is revisiting Q2 from HW4 but fitting these values as a multivariate response. After enjoying numerous Bridger Bowl powder days during your time at MSU, you have received a job offer in New Mexico. You decision hinges on the quality of snow at your potential new home mountain, Taos.
According to https://www.onthesnow.com/new-mexico/taos-ski-valley/historical-snowfall.html annual snowfall totals can be obtained.
Below are the snowfall totals for Taos and Bridger Bowl for the last nine years.
taos <- c(78,192,169,179,191,204,197,116,195)
bridger <- c(271,209,228,166,316,254,344,319,247)
Specifically you are interested in computing three probabilistic statements.
Write out the sampling model and define all parameters. Make sure to specify values in the prior distributions.
Fit a multivariate Gibbs sampler. Include your code in-line here and plot: the posterior distribution for θ (this will be two dimensional) and the marginal distributions for θbridger and θtaos. Also include the posteriors means for the components in the covariance matrix.
Answer the three probabilistic questions above.
