WebbWe find that TGWR performs better than OLS with fixed effects and leads to less regressive assessed values than OLS. In many cases, TGWR performs better than GWR that ignores the time dimension. In at least one specification, several suburban and rural towns meet the IAAO Coefficient of Dispersion cutoffs for acceptable accuracy. Webb7 dec. 2024 · These scores mean the assessments were highly inaccurate. In 2015, the coefficient of dispersion was 66. Standards set by the IAAO say any PRD score above 1.03 shows the assessments are regressive, meaning the system is unfair to people who own low-valued property.

WebbThe COEFFICIENT OF DISPERSION (COD) is the most common measure of uniformity in sales ratio studies. It indicates how tightly the ratios are clustered around the median ratio. The COD is a proportional measure found by taking the average of the absolute deviation of ratios about the median, and dividing by the median ratio.

These considerations can be measured in terms of the Coefficient of Dispersion (COD) and the Price-Related Differential (PRD), as described by the International Association of Assessing Officers (IAAO). “Uniformity” is measured with the COD (IAAO, 2013), while “vertical equity” is measured with the PRD (IAAO, 2003). sweatshirt with cut rounded hemlineWebbacceptable level for the coefficient of dispersion depends upon the type of properties being reviewed. According to IAAO, coefficients of dispersion should typically be 20% or less, depending on the types of properties being valued.
