Spatial Prediction of Aadt in Unmeasured Locations 3 by Universal Kriging

27 28 ABSTRACT 29 30 This work explores the application of kriging methods for prediction of average daily traffic 31 counts across the Texas network. Results based on Euclidean distances are compared to those 32 using network distances, and both allow for strategic spatial interpolation of count values while 33 controlling for each roadway's functional classification, lane count, speed limit, ...

Prediction and Calibration in Generalized Linear Models*

This paper concerns prediction and calibration in generalized linear models. A new predictive procedure, giving improved prediction intervals, is briefly reviewed and further theoretical results, useful for calculations, are presented. Indeed , the calibration problem is faced within the classical approach and a suitable solution is obtained by inverting the associated improved prediction proce...

Nonparametric Functional Calibration of Computer Models

Standard methods in computer model calibration treat the calibration parameters as constant throughout the domain of control inputs. In many applications, systematic variation may cause the best values for the calibration parameters to change across different settings. When not accounted for in the code, this variation can make the computer model inadequate. We propose a framework for modeling ...

Bayesian Calibration of Complex Computer Models

We consider prediction and uncertainty analysis for systems which are approximated using complex mathematical codes. Such models, implemented as computer codes, are often generic in the sense that by suitable choice of some of the model's input parameters the code can be used to predict behaviour of the system in a variety of speciic applications. However, in any speciic application the values ...
