That table is the customary way to present regression results in economic research (nber.org, ssrn.com, ...) There is no graphical way to represent what variables are statistically significant and their various correlations.
I suggest that you educate yourself on the subject with the following link (http://www.j-bradford-delong.net/movable_type/Econ_113/regre...)
Hi David,
Nice post by the way. The results are really suggestive but what leaves me wondering is that there is a million of things that can be going on at the same time.
Also, why did you ended up doing ILRS/LAD instead of more straightforward methods?
