• Does Head evaluate its argument?

  From , I learned that there are some functions which evaluate their argument and others which don't:  I wondered about Head. Here everything looks logic ...f= Expr(x=2); Substitute(NameExpr(f),Expr(x), Expr(y)); Head(f);Head is not like Substitute, I can directly use the function name as an argument  - and Head returns the head of the expression: Assign()  After checking some other functions which...

• PLS

  New to PLS and confused as to the following: when I run the PLS and ask for results  for two factors, I  get two rows for each Y (in this case metabolites). I must  be interpreting the results wrong, as I do not expect two rows for each metabolite, with a total of four different scores, two apparently corresponding to each factor.

• Looking for help building a CCD RSM DOE with both blocks and custom axial levels.

  Hello,I'm currently trying to build a response surface model using a central composite design, but I want to add both blocks and custom axial points. My study has 3 continuous factors and will need to be split into 2 blocks of experimenting, and I prefer to set my axial levels to 2.0 instead of 1.0 to explore more of the design space and help correct for non-linearity a little better. I can build ...

• Not sure how to use "Weight" in "Analyze"

  I want to do something really simple. For simplicity's sake, assume I have two groups, let's say with N=2,000 in group 1 and N=3,000 in group 2. I'd like to compute an overall mean of a variable Y that is collected for each group. Y's mean in group 1 is 4 and in group 2 is 8. The overall mean here would be the unweighted mean and not the weighted mean–it should be 6. I might have thought that I sh...
