Evaluating Spatial Model Accuracy In Mass Real Estate Appraisal: A Comparison Of Geographically Weighted Regression And The Spatial Lag Model, Paul E. Bidanset, John R. Lombard Jan 2014

Evaluating Spatial Model Accuracy In Mass Real Estate Appraisal: A Comparison Of Geographically Weighted Regression And The Spatial Lag Model, Paul E. Bidanset, John R. Lombard

School of Public Service Faculty Publications

Geographically weighted regression (GWR) has been shown to greatly increase the performance of ordinary least squares-based appraisal models, specifically regarding industry standard measurements of equity, namely the price-related differential and the coefficient of dispersion (COD; Borst and McCluskey, 2008; Lockwood and Rossini, 2011; McCluskey et al., 2013; Moore, 2009; Moore and Myers, 2010). Additional spatial regression models, such as spatial lag models (SLMs), have shown to improve multiple regression real estate models that suffer from spatial heterogeneity (Wilhelmsson, 2002). This research is performed using arms-length residential sales from 2010 to 2012 in Norfolk, Virginia, and compares the performance of GWR ...


The Effect Of Kernel And Bandwidth Specification In Geographically Weighted Regression Models On The Accuracy And Uniformity Of Mass Real Estate Appraisal, Paul E. Bidanset, John R. Lombard Jan 2014

The Effect Of Kernel And Bandwidth Specification In Geographically Weighted Regression Models On The Accuracy And Uniformity Of Mass Real Estate Appraisal, Paul E. Bidanset, John R. Lombard

School of Public Service Faculty Publications

The article presents a study which examines the performance of kernel and bandwidth specification in geographically weighted regression (GWR) models in mass real estate appraisal. The kernels employed in the study are the bi-square kernel and the Gaussian kernel. Data from the sales of single-family homes in Norfolk, Virginia from 2010 to 2012 are highlighted.


Organizational Climate And Commitment: A Case Study Of An Urban Nonprofit Organization, William Sawyer Grant Jan 2002

Organizational Climate And Commitment: A Case Study Of An Urban Nonprofit Organization, William Sawyer Grant

Theses and Dissertations in Urban Services - Urban Management

This qualitative study investigates the relationship between the two constructs: Organizational Climate and Organizational Commitment.

Litwin and Stringer (1968) suggested that a molar model is needed to explain employee behavior and motivation. Climate was proposed as this molar construct. Research concerning Organizational Climate resulted in multiple definitions and little consensus concerning the number and use of multiple dimensions of this construct. The almost exclusive use of survey methods coupled with methodological confusion with Organizational Culture created difficulty with the use of this important construct.

Organizational Commitment research resulted in a number of competing definitions. Research by Meyer and Allen (1997 ...
