Add Deming regression to an existing regression procedure (such as PROC REG or Proc GLM). Include an option for weighted Deming regression.
I'm looking for a weighted Deming Regression macro for SAS. I would be very useful to have Deming, Weighted Deming and Passing-Bablok options for proc GLM or proc REG. Basic assay method comparison procedures used to evaluation IVD's and laboratory assays.
Given the FDA's acceptance of Deming Regression for method comparison studies, I'm surprised not to find a PROC that can do it. Is it available in any of the clinical trial solutions provided by SAS, outside of SAS/STAT etc?
Seems people are left to write their own macros, as in: http://analytics.ncsu.edu/sesug/2009/CC014.Deal.pdf
Would be nice to have SAS provide it, since many folks turn to alternative analytic tools when they need to run a Deming regression (e.g. Minitab).
