Interpreting mutliple regression Beta is only way?

2002-01-16 Thread Wuzzy
If your beta coefficients are on different scales: like you want to know whether temperature or pressure are affecting your bread baking more, Is the way to do this using Beta coefficients calculated as Beta=beta*SDx/SDy (SDx=standard deviation of each x) (SDy=standard deviation of the dependant
