Projections in Model Space: Multi-model Inference Beyond Model Averaging
نویسندگان
چکیده
A reviewer of the manuscript challenged us to do two things. First, to move beyond simple likelihood ratio examples and show how evidential ideas are used in the practice of science. And, second to solve some deep problem in ecology using this framework. To answer the first challenge, we discuss information criteria differences as a natural extension of the likelihood ratio that overcomes many of the complexities of real data analysis. To answer the second more substantive challenge, we then extend the information criterion model comparison framework to much more effectively utilize the information in multiple models, and contrast this approach with model averaging, the currently dominant method of incorporating information from multiple models (Burnham and Anderson 2002). Model averaging is a confirmation-based-approach. Because of limitations in both time and allowable word count, this will be a sketch of a solution. We deeply appreciate the reviewer’s challenge because the work it has forced us to do has been very rewarding.

New Approaches in 3D Geomechanical Earth Modeling
In this paper two new approaches for building 3D Geomechanical Earth Model (GEM) were introduced. The first method is a hybrid of geostatistical estimators, Bayesian inference, Markov chain and Monte Carlo, which is called Model Based Geostatistics (MBG). It has utilized to achieve more accurate geomechanical model and condition the model and parameters of variogram. The second approach is the ...

ABSTRACT: In this study, adaptive neuro-fuzzy inference system, and feed forward neural network as two artificial intelligence-based models along with conventional multiple linear regression model were used to predict the multi-station modelling of dissolve oxygen concentration at the downstream of Mathura City in India. The data used are dissolved oxygen, pH, biological oxygen demand and water...
متن کاملThe use of wavelet - artificial neural network and adaptive neuro fuzzy inference system models to predict monthly precipitation
Precipitation forecasting due to its random nature in space and time always faced with many problems and this uncertainty reduces the validity of the forecasting model. Nowadays nonlinear networks as intelligent systems to predict such complex phenomena are widely used. One of the methods that have been considered in recent years in the fields of hydrology is use of wavelet transform as a moder...
