Dear R Users,
Recently I began to use R. I`m interested about comparing several
regression curves. I found the package sm and the function sm.ancova which
I understand allows me to do this. I applied this function to my data
(seven regression curves) and I found that there are significant
differences. Nevertheless, when I want to find out where are the
differences, the package tells that it allows only paired comparisons.
Do you have any idea if this package makes only paired comparisons or if
does it allow to perform multiple comparisons?
Somebody suggested me also the Wald test to compare this but I am not
familia with it.
Thanks in advance!
