Bayesian Total Error Analysis


The assumption that the storm-dependent parameters are log-normally distributed is only partially supported by the data, which suggests that the parameter hyper-distributions have thicker tails.

The system returned: (22) Invalid argument The remote host or network may be down. Of particular significance is the use of posterior diagnostics to test the key assumptions about the data and model errors. A case study calibrating a six-parameter CRR model to daily data from the Abercrombie catchment (Australia) demonstrates the considerable potential of this approach. This study works towards the goal of developing a robust framework for dealing with these sources of error and focuses on model error.

This paper argues that the fluxes in CRR models should be treated as stochastic quantities because their estimation involves spatial and temporal averaging. It provides a very general framework for calibration and prediction, as well as for testing hypotheses regarding model structure and data uncertainty. GlobalView NOVA.

The hypothesis advanced in this paper is that CRR model error can be characterised by storm-dependent random variation of one or more CRR model parameters. Bayesian Analysis Pdf The characterisation of model error in CRR modelling has been thwarted by the convenient but indefensible treatment of CRR models as deterministic descriptions of catchment dynamics.
