C -3.481203


does the above mean that the price elasticity and income elasticity are 0.412 and 0.703, or that they are -0.412 and -0.703?

thanks

anybody have any idea? even a short answer will do..

They have positive sign. So it's "+0.412459" and "+0.7035123".
(-1) means the lag, not the sign!
The second has got a good elasticity, it's near 1, value of perfect transmission. When sales change by 1%, income variation is of +0,7%. Remember that the prices have to be logged.
