Errors-in-variables regression: is it valid to pool data from three sites?
EDIT: Given the suggestion of Bill Huber I plan to look at bounds on the errors-in-variables regression by regression both y on x and x on y. … So I will give them both analyses and request at least that they tell the FDA that in addition to do the bootstrap I did inverse regression and bounded the Deming regressions which I think is more appropriate …

What is the advantage of reducing dimensionality of predictors for the purposes of regression?
Examples of such techniques include Sliced Inverse Regression, Principal Hessian Directions, Sliced Average Variance Estimation, Kernel Sliced Inverse Regression, Principal Components Regression, etc. … Is this SDR/DRR + Regression on a low-dim dataset faster than only regression on a high-dim dataset? …

Errors-in-variables regression: is it valid to pool data from three sites?
The usual solution in such cases is "inverse regression" (as described, for instance, in Draper & Smith, Applied Regression Analysis (Second Edition), section 1.7). … Otherwise, these components of variance may need explicitly to be modeled and estimated in the inverse regression analysis. …

I was trying to write an answer for this question:

Inverse Regression vs Reverse Regression
This is what I mean by inverse regression.
However I've seen since been playing with some toy models and I'm starting to see that the 'wrong' method produces much better predictions. … Are there other situations where inverse regression actually outperforms? …
