Sorry for possible cross posting but it seems that my previous message was send as HTML and then scrubbed.
Dear list members,
I want to use a GLM with an unbalanced factor and continuous variables.
My factor F has 12 unbalanced levels:
A B C D E F G H I J K L
1 1 4 6 6 1 2 1 2 3 1 3
I thus want to code contrasts appropriatly.
I have looked in R documentations and R-help archives without finding the information for unbalanced designs.
Any help will be very useful.
Thanks you very much.
