WebDeming is useful in situations where both X & Y are measured with error. The use of Deming regression is beneficial when comparing to methods for measuring the same … WebDeming regression Description Allows to perform method comparison using the Deming regression model (Cornbleet & Gochman, 1979). Whereas the ordinary linear regression method assumes that only the Y measurements are associated with random measurement errors, the Deming method takes measurement errors for both methods into account. …
