Yes, in fact, I have used SAS . It happens that it is more convenient for me to use R than SAS; I have hoped that I could easily use R to get what I need (in the future) but there seems to be no easy way to do so, Thanks,Stanley Shulman ---------- Original Message ---------- From: Douglas Bates <bates at stat.wisc.edu> To: "m51988mnew at juno.com" <m51988mnew at juno.com>, r-sig-mixed-models at r-project.org Subject: Re: [R-sig-ME] Fw: question about Type III sums of squares as computed in "CAR' Date: Fri, 20 Nov 2015 17:08:58 +0000 I don't think your data, code, etc. made it through to the list. If you need the SAS results, wouldn't it be easier to use SAS to get them?

Each occupation has one measurement per day. The 11 sampling days are at 4 sites: 3 days at 3 of the sites and 2 days at 1 site. In addition, there were three workers who did the second occupation , labelled 6,7,8, for the variable idb. I need the SAS type III sums of squares for each of the variables in the model, but you can see the error message in the R code: there are aliased coefficients in the model In SAS I believe that this problem is dealt with by placing constraints on the parameters.I would appreciate any suggestions. I think that maybe I am formulating the model wrong.

Maybe I am using the program wrong. SAS gives the Type III sums of squares.
