Hi all. Has anyone ever done a Deming Regression in R? I'm wondering if there's a simple way to do it. Thanks for all your help! -Ed -- View this message in context: http://www.nabble.com/Deming-Regression-tp17949318p17949318.html Sent from the R help mailing list archive at Nabble.com.

Hi, I have a dataset which has var1 from 1 sourse and var2 from 2 different methods. I need a new variable such that var2 values from both methods can beused as 1 variable. I believe deming regression can be used to do this. I just don't know how to do it. My data looks like: idvar1var2method1var2method2 11.22.1NA 21.62.4NA 31.52.2NA 41.3NA2.8 51.6NA3.1 61.4NA2.7 Please help. Sincerely, Devon [[alternative HTML version deleted]]

Dear all, After a thorough research, I still find myself unable to find a function that does linear regression of 2 vectors of data using the "total least squares", also called "orthogonal regression" (see : http://en.wikipedia.org/wiki/Total_least_squares) instead of the "ordinary least squares" method. Indeed, the "lm" function has a

...ifferent from 18.20788. On the contrary, the result is more like the one from a general positive-definite variance-covariance structure. Can anyone tell me why I did not see a compound symmetry structure from the BLUPs predictors of the random effects or if I am doing something wrong? Thank you!

...measurement error) and use that to do this conversion. It seems to me that since we can only observe error-prone x, and we should be predicting the expected value of error-prone y (i.e E[y | x]). Therefore, we can simply use the ordinary regression equation. However, I have seen papers using the Deming's orthogonal regression or something equivalent in the clinical chemistry literature to address this problem. Deming's method would make sense if I am interested in obtaining the functional relationship between X and Y (the true values of two assays), but I don't see why I should care...

I wanna to do a Regression type 2 or Regression with X measured with error....anybody knows how can i make it in R?? thanks! -- View this message in context: http://r.789695.n4.nabble.com/Regression-type-2-x-measured-with-error-tp3251875p3251875.html Sent from the R help mailing list archive at Nabble.com.

I am trying to understand better an analysis mean RT in various conditions in a within subjects design with the overall mean RT / subject as one of the factors. LME seems to be the right way to do this. using something like m<- lme(rt~ a *b *subjectRT, random= ~1|subject) and then anova(m,type = "marginal"). My understanding is that lme is an easy interface for dummy coding

...is an R function (package) to fit a two-terms exponential model like y = a*exp(bx) + c*exp(dx) where y is dependent variable and x is independent variable. MATLAB has a Curve Fitting Toolbox to implement this fitting, but I don't know if there is an R package for this fitting. Thank you! Deming Mi
