Eins,
You can generate data from a pre-specified regression equation. For example, if you were interested in generating data from a regression equation which assumed a moderation effect (e.g., interaction between two binary variables), something like this would work:
set seed 98765432.
new file.
inp pro.
loop id = 1 to 1000.
comp x1 = rv.bernoulli(0.50).
comp x2 = rv.bernoulli(0.50).
comp y = 0.5 + 1.3*x1 + 2.6*x2 + 1.4*x1*x2 + rv.normal(0,1).
end case.
end loop.
end file.
end inp pro.
exe.
