equivalence test for regression coefficients

[yesa]

here are the results

The analysis of Covariance plot shows you the slopes of each of the values of atg_rder

Ok, thanks. But my original question is still not solved. I need to test if the estimated coefficients are significantly different from each other or not? I have heard about Wald test for this. But don't know how to write the code in SAS.

with best regards.

The F-test is the test you are asking for. Since the Pr>F is <0.0001, the slopes are significantly different. I don't think the Wald test applies here.
