	Deming regression - Wikipedia, the free encyclopedia
		Deming regression is a method of linear regression that finds a line of best fit for a set of related data.
		If both sets of data contained error, for instance the relationship between concentrations of two substances in blood, Deming regression would be more appropriate.
		The disadvantage with Deming regression, is that it is mathematically more complex to do.

		Regression statistics can provide estimates of these components of systematic error by the y-intercept and slope, as well as estimation of the overall systematic error or bias at any decision level concentration of interest by calculation from the regression equation.
		Regression statistics are preferred over t-test statistics in order to calculate the systematic error at any decision level, as well as getting estimates of the proportional and constant components of systematic error.
		In Deming regression, the errors between methods are assigned to both methods in proportion to the variances of the methods.

		Deming was never very pleased with the NBQA, I understand, and accoring to Juran's book, "Architecht of Quality", perhaps the reasons had to do with the designers of the NBQA never quite understood the Deming philosophy.

		Deming regression is a method of linearregression that finds a line of best fit for a set of related data.
		It differs from simple linear regression in that itaccounts for error in both the 'x' and the 'y'-axis.
		For instance, if the x-axis data is known to have no error, but the y data does, (such as a population estimate (y), at aknown time (x)), simple linear regression would work.

		Deming is credited with institutionalizing a system of strategic manfacturing which is responsible for the formidable Japanese presence in the world market (Yoshida 1989).
		Dr. Deming's principles were based on the premise that most product defects resulted from management shortcomings rather than careless workers, and the inspection after the fact was inferior to designing processes that would produce better quality (Yates 1992).
		Deming's management principles were believed to help enhance morale and job satisfaction; to contribute to organizational goals of increased productivity, reduced costs; and to improve the quality of the operation and the products.

		In the November 1998 issue of Clinical Chemistry, Stockl, Dewitte, and Thienpont (1) provide an interesting discussion of linear regression techniques in method-comparison studies, pointing out that the quality of the data may be more important than the quality of the regression technique (e.g., ordinary linear regression vs Deming regression vs Passing-Bablock regression).
		Different regression techniques may be appropriate, depending on the characteristics of the data - particularly the analytical range that is covered relative to the test values that are critical for medical applications.
		Note that these regression techniques are not standard in ordinary statistics programs, but they are available in special programs designed for laboratory method evaluation studies.

	Deming Web Site - Blomquist Article
		To quote Deming: "Our aim in production should be to improve the process to the point where its distribution is so narrow, the specifications are lost beyond the horizon." That is, we should learn enough about our processes to be able to set process target nominals such that the variation around those nominals is minimal.
		It also has somewhat diminished the impact of the Deming objective by translating its goals so that it is expressed in terms of parts per million defects, rather than minimized variation around the target.
		Just as scatter plot techniques were used long before regression and other statistical methods were devised, so also the intuitive interpretation of those scatter plots can be made to discover the nature of variation transmission without sophisticated solutions.

		If you have prior measurement error estimates, so you know that Deming regression is appropriate, then I would think that you could just as easily do this using PROC CALIS.
