• How to compare two regression coefficients?

  Hi, i have a data set with:
  2 groups: A and B
  for each case, 2 variables: var1 and var2
  i'd like to compare regression coefficient R2 and R2 (between the 2 groups) for the regression curves: var1=R1*var2 and var2=R2*var2
  
  I know how to obtain R1 and R2 (fit y by x (var2=y and var1=x), group by "group", but I don't know how to compare R& and R2 to say there are not equal (or R1>R2).
  
  Thank's for your help...

  Thanks!

I have a table with values in it, and I would like to create a new table with the same columns and rows, but with a formula applied to the entire new table. I have thousands of columns, so it is not practical to apply the formula column by column. I would really appreciate any suggestions that anyone could offer.

• Multiple range tests: How can I change the cutoff level from alpha=0.05?

  When I run a multiple range test from the “Fit Model” on the “Analyze” main menu of either JMP 7 or JMP 8 (which can be done by running the model, expanding the “Effect Details” section of the output and then clicking on “LS Means Student’s t” or “LS Means Tukey HSD” depending on the type of test I want), I get a set of pairwise comparisons performed at the 5% significance level.
  
  I need to change t...
