Inferential statistics, at its core, is concerned with making inferences about a population based on a sample drawn from that population. It involves analyzing sample data to draw conclusions about the broader population because the broader population is either too large to analyze, unknown, or hypothetical. While invaluable in many scientific disciplines and research contexts, […]
The second of our “foibles” in USPAP may be from that same paragraph on page (ii), noted last week. This paragraph effectively sets the mission statement for the Appraisal Foundation. The paragraph is titled: “ABOUT THE APPRAISAL FOUNDATION.” It states the AF provides “guidance on recognized valuation methods and techniques for all valuation professionals.” [Emphases […]
“I never make adjustments,” said the MAI who first trained me. He was a top litigation appraiser. He explained that if he made an adjustment he had no way to explain how he got the number when cross-examined by the opposing attorney. Instead, he used what is called ‘qualitative analysis.’ The Appraisal of Real Estate […]
EBV (Evidence Based Valuation) principles continue to update from legacy “appraisal” practices. Here we hope to have a quick look at the upsides and downsides of EBV, compared to traditional, judgment-based “methods and techniques.” Editor’s Note: This is Standards, part 3.16 of George Dell’s series on How Do I Move to EBV? Links to the […]
We’ve seen the standard which requires an appraiser to use ‘correct’ methods (whatever those may be). And which also requires the appraiser to use ‘sufficient’ care (whatever that is). All part of the legacy USPAP Uniform Standards of Professional Appraisal Practice. Be correct and be careful! Editor’s Note: This is Standards, part 3.15 of George […]
The USPAP “Competency Rule” is straightforward. It says you must be competent! For any given assignment, “being competent” requires the appraiser to: “properly” identify the problem; have knowledge and experience to be competent; recognize and comply with applicable laws and regulations. Editor’s Note: This is Standards, part 3.9 of George Dell’s series on How Do […]
Standards: Credible v Reliable. Editor’s Note: This is Standards, part 3.4 of George Dell’s series on How Do I Move to EBV? Links to the earlier posts are here. Here, we specifically note how the goal of having valuation standards can be updated to reflect today’s complete data, and computation analytics can be optimized for […]
Standards enforce appraisal review as well as development and reporting. Editor’s Note: This is Standards, part 3.3 of George Dell’s series on How Do I Move to EBV? Links to the earlier posts are here. This is the third part topic of the larger topic of how standards may help or hinder the move into […]
Evidence Based Valuation – EBV is the future for valuation professionals. It requires the appraiser’s experience, judgment, and knowledge. It’s not hard, just new. EBV captures the huge advantages of modern technology: computer power, open-source software, and market visualization. EBV provides an exciting learning path toward better service, personal satisfaction, and income security. Most importantly, […]
Current efforts in the regulation of appraisal quality and fairness are fettered by obsolete appraisal methods. Traditional appraisal methods were designed to tackle sparse, subjective, non-electronic data. These vintage practices enable bias, hinder diversity initiatives, and conceal risk quantification. We have written about the “Five Frictions” hindering improvement in regulated appraisal valuation. Most other valuation […]
Appraiser credibility continues to decay over time. Even during the great runup in prices, and now the spotty, often rapid rundown in prices – residential appraisers mostly turned a blind eye to the need for this critical “time adjustment.” Non-residential appraisers have yet to see the coming value shifts. Shamefully, a time adjustment, (or market […]
Market value, of course! Or is it? The great recession, and things like that, which come around every 12-15 years, all concur with the ‘accepted’ definition of market value, as written in the USPAP book Advisory Opinion 30. In short, the definition requires: Most probable price Competitive and open market Prudent and knowledgeable consumers No […]
To regulate or improve something, you first measure it. The word credible appears in the most recent version of USPAP (©1999) some 276 times. The Uniform Standards of Professional Appraisal Practice as published from time to time by the Appraisal Foundation. The word credibility is used an additional 39 times, specifically as a measure of […]
Evidence is shortly defined as “Something that shows proof.” It’s precisely defined in the law, and also addressed in philosophy and epistemology. Epistemology deals with methods, validity, and scope in the theory of knowledge. In the philosophy of science, evidence is what confirms (or not) your hypothesis. Evidence justifies belief, but only if respected. It […]
Editor’s Note: This is Part 1 of a new series on Bias. Easy – Just don’t be biased. Don’t even think about it! Alternately, we can have the government regulate and require it! To know what ‘unbiasedness’ is, and how to achieve it, we have to be able to measure it. We cannot enforce anything, […]
