X is a continuous explanatory variable; Y is a continuous dependent variable, Z1 and Z2 are dichotomous variables. An example of the data is: Y X Z1 Z2 0.38448 11134.94 1 0 0.42872 10280.34 1 0 0.45391 12595.40 1 0 0.26954 7461.27 1 0 0.49276 13352.59 1 0 1.09706 33692.40 1 0 0.31529 8987.04 1 0 0.20629 5190.80 1 0 0.49011 15962.34 1 0 0.23585 6454.96 1 0 0.54901 14717.25 1 0 0.26269 7757.72 1 0 0.62173 14394.44 1 0 0.60383 18041.02 1 0 0.47756 13406.98 1 0 0.44168 11272.19 1 0 0.09205 2349.10 1 0 0.32221 8780.78 1 0 0.19188 5586.24 1 0 0.19467 4797.40 1 0 0.08793 2121.80 1 0 0.13247 3744.60 1 0 0.22353 5683.04 1 0 0.09343 2175.01 1 0 0.47902 13764.63 0 1 0.21821 5703.75 0 1 0.08321 1954.22 0 1 0.15906 4490.16 0 1 0.50418 15138.00 0 1 0.08847 2178.00 0 1 0.16686 4471.20 0 1 0.17571 4435.76 0 1 0.27287 7337.30 0 1 0.05631 1362.18 0 1 0.13135 3717.12 0 1 0.41391 11741.91 0 1 0.13025 3207.24 0 1 0.34055 10097.38 0 1 0.32904 8126.60 0 1 0.47509 12354.75 0 1 0.80383 23064.00 0 1 0.66650 18758.08 0 1 ...

I want to answer the following questions: are the lines coincident? are the slopes different? are the intercepts different? For that, I have used the following piece of code: PROC REG DATA=ALL;         MODEL Y = X Z1 Z2  XZ1 XZ2 Z1Z2;         INTERCEP: TEST Z1, Z2;         SLOPE: TEST XZ1, XZ2;         COINCID: TEST Z1, Z2, XZ1, XZ2;         RUN; How can I interpret the results?   Comments will be deeply appreciated...   Best,   Santiago ...
