Abstract
  • Markov Chain Monte Carlo methods may be used to determine normalizations and moments of distributions. However, these methods may perform poorly when starting from distributions that have little overlap with the target. We develop a homotopy based iterative process of incremental importance sampling to normalize distributions when observations can only be made from those distributions that differ from target. In addition to this topic, discussions are included of my experience in the NSF Risk and Uncertainty Traineeship Program (NRT) applying mathematical knowledge to a transdisciplinary study of the Dungeness crab.
