How to fit multiple independent slopes and intercepts with the GLM module?

Questions

Thanks, that works. But how can I transform the estimated parameters into intercepts and slopes for the two individual curves (of the two conditions)?

So I fitted:

group + slope + group : slope

And now I would like to turn these components into:

group1_slope, group1_intercept,
group2_slope, group2_intercept,

It’s probably very obvious but I guess I’m missing something …

Thanks a lot!
