[R] Ad Hoc comparison non parametric ANCOVA
Dear R Users, Recently I began to use R. I`m interested about comparing several regression curves. REcently 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? Thanks in advance! [[alternative HTML version deleted]]

Somebody suggested me also the Wald test to compare this but I am not familia with it. Thanks in advance! [[alternative HTML version deleted]]
