| Nov 11, 2011 at 16:17 | comment | added | varty | What is the equation for the regression line? Could you please edit the question to write the correct equation? That should help you about the intercept. | |
| Nov 11, 2011 at 16:01 | comment | added | upabove | I though about dividing 30000 by 66 to get the 1 unit and then using that as an intercept but i'm not sure if that's enough.. | |
| Nov 11, 2011 at 15:43 | comment | added | varty | @Dbr In that case you should edit the question to make it accurate/correct. You are not using all the information that has been given to you. What about the information on the earnings of someone who is 66 inches? | |
| Nov 11, 2011 at 15:30 | comment | added | upabove | @varty yes I left that out so its log(earnings)=0.8*log(height)+error but I still don't know how to calculate the intercept and how to proceed to the second question | |
| Nov 11, 2011 at 15:27 | comment | added | varty | Hint: The question says that log earnings can be predicted from log height. So, your answer is along the right lines but you are missing some logs here and there. | |

| Nov 11, 2011 at 11:19 | comment | added | upabove | yes I also found the % strange but I just assumed that it means a 1 unit increase | |
| Nov 11, 2011 at 11:10 | comment | added | rolando2 | It's an odd example in several ways. Normally we'd calculate b as the change in Y associated with a change of 1 (rather than of a certain %) in X. I don't see how to handle that % change as indicated. Also please note that the unstandardized coefficient, b, is different from the standardized one, Beta. | |
