NCSS
Real Estate Appraisal
Introduction
NCSS has three procedures
that were developed just for appraisal work. These are the Comparables
procedure, the Sales Ratio procedure, and the Hybrid (Feedback) Model
procedure. In addition to the common descriptive statistics, NCSS
also provides statistics that are of particular interest to appraisers.
These include the coefficient of dispersion (COD), the weighted mean (W
Mean), and the price related differential (PRD). These values are
provided in useful report formats that break the results down by several
category variables such as neighborhood and/or property type.
Sales Ratio Reports
NCSS has a Sales Ratio procedure that automatically provides the
specialized statistics used in appraisal. The output includes the mean,
median, weighted mean (W Mean), coefficient of dispersion (COD), and
price related differential (PRD). These statistics may be broken down by
category variables such as property type and/or neighborhood.
Comparables Reports
NCSS has a Comparables procedure that uses special computer
algorithms to find a set of comparables for a subject property, adjust
their sales prices appropriately, and output a report that summarizes
results for a few of the closest properties. You have complete control
over which variables are used and how market value adjustments are
applied.
Hybrid Appraisal Model
NCSS has a Nonlinear Regression procedure that lets you apply
special multiplicative-adjustment models. It also has an easy-to-use
implementation of the Hybrid Appraisal Model designed specifically for
appraisal work.

Accuracy
We at NCSS have put a
great deal of effort into finding the most
accurate algorithms possible. The programs have
been tested and verified over and over, both by
us and by our customers. Each routine has been
verified against textbooks, journal articles,
and, where possible, other software. NCSS is one
of the most accurate statistical analysis
programs available. NCSS calculates with
seventeen-digit, double-precision accuracy. |
