The main idea is that the longer the bar or the larger the coefficient, the greater the impact that particular input has on the output that you are analyzing. (palisade.com)
A positive coefficient, with bar extending to the right, indicates that this input has a positive impact: increasing this input will increase the output. (palisade.com)
For the output, Input A has a regression coefficient (standard b) of 0.78. (palisade.com)
To get from that coefficient to the actual coefficient in terms of units of input and units of output, multiply by the SD of the output and divide by the SD of the input. (palisade.com)
For example, if Input A has a mapped coefficient of 10,023.53, it means that an increase of k standard deviations in Input A produces an increase of 10,023.53 * k units (not standard deviations) in the output. (palisade.com)
