Bayesian Variogram Modeling for an Isotropic Spatial Process
- M. Ecker, A. Gelfand
- Mathematics
- 1 December 1997
Here we adopt a Bayesian approach to variogram modeling. In particular, we seek to analyze a recent dataset of scallop catches. We have the results of the analysis of an earlier dataset from the… Expand
The Dynamics of Location in Home Price
- A. Gelfand, M. Ecker, J. Knight, C. F. Sirmans
- Economics
- 17 February 2004
It is well established that house prices are dynamic. It is also axiomatic that location influences such selling prices, motivating our objective of incorporating spatial information in explaining… Expand
Landscape, demographic and climatic associations with human West Nile virus occurrence regionally in 2012 in the United States of America.
- John P DeGroote, R. Sugumaran, M. Ecker
- Geography, Medicine
- Geospatial health
- 1 November 2014
After several years of low West Nile virus (WNV) occurrence in the United States of America (USA), 2012 witnessed large outbreaks in several parts of the country. In order to understand the outbreak… Expand
Bayesian Modeling and Inference for Geometrically Anisotropic Spatial Data
- M. Ecker, A. Gelfand
- Computer Science
- 1999
TLDR
Spatial modeling and prediction under stationary non-geometric range anisotropy
- M. Ecker, A. Gelfand
- Mathematics
- Environmental and Ecological Statistics
- 1 June 2003
For modeling spatial processes, we propose a rich parametric class of stationary range anisotropic covariance structures that, when applied in R2, greatly increases the scope of variogram contors.… Expand
A Statistical Examination of Water Quality in Two Iowa Lakes
- E. Carlson, M. Ecker
- Environmental Science
- 14 September 2002
Water quality has become and important issue in the state of Iowa as well as across the entire United States. Two Iowa Lakes, Silver Lake and Casey Lake were chosen for study by a team of biologists,… Expand
Bayesian Spatial Modeling of Housing Prices Subject to a Localized Externality
- M. Ecker, V. D. Oliveira
- Mathematics
- 2 May 2008
This work proposes a non stationary random field model to describe the spatial variability of housing prices that are affected by a localized externality. The model allows for the effect of the… Expand
An analysis of the impact of swine CAFOs on the value of nearby houses
- Hans R. Isakson, M. Ecker
- Economics
- 1 November 2008
The impact of 39 swine confined or concentrated animal feeding operations (CAFOs) in Black Hawk County, Iowa on 5,822 house sales is explored by introducing a new variable that more accurately… Expand
An Analysis of the Influence of Location in the Market for Undeveloped Urban Fringe Land
- Hans R. Isakson, M. Ecker
- Economics
- Land Economics
- 1 February 2001
This paper blends and extends the Colwell and Munneke (1997) and Isakson (1997) models of urban land values to include a spatiotemporal plattage component. By including a monocentric term in the… Expand
Remote Sensing Calibration of Casey Lake and Silver Lake
- Krista Ellyson, M. Ecker
- Environmental Science
- 17 June 2005
This project examines two Iowa lakes to explore the feasibility of using remote sensing technologies for assessing water quality in lieu of actual ground samples. We demonstrate that a principal… Expand
