mboost: Interpreting coefficients from glmboost if center=TRUE
...tering improves the
predictions made by the model, so this is an issue worth pursuing for
me.
Below is output from running the exact same data in exactly the same
way, only differing by whether the "center" bit is flipped or not:
Output with center=TRUE:
[(Intercept)] => -0.04543632
[painscore] => 0.007553608
[Offset] => -0.546520621809327
Output with center=FALSE:
[(Intercept)] => -0.989742
[painscore] => 0.001342585
[Offset] => -0.546520621809327
The mean of painscore is 741. It seems to me that for center=FALSE,
mboost should modify the intercept by subtracting 741*0....
