Bayesian Hierarchical Model BHM Ralph F Milliff CIRES University of Colorado Jerome Fiechter Ocean Sciences UC Santa Cruz Christopher K Wikle Statistics University of Missouri. This is useful only in the case where we know the precise model family and parameter values for the situation of interest But this is the exception not the rul e for both scienti64257c inquiry and human learning inference Most of the time we are in g Gaussian so only the parameters eg mean and variance need to be estimated Maximum Likelihood Bayesian Estimation Non parametric density estimation Assume NO knowledge about the density Kernel Density Estimation Nearest Neighbor Rule brPage 3br CSC What is the idea behind modeling real world phenomena Mathemat ically modeling an aspect of the real world enables us to better understand it and better explain it and perhaps enables us to reproduce it either on a large scale or on a simpli64257ed Options for ocean health and societal adaptation.
