Question

A regression analysis was performed, with partial results shown below, along with various plots.

In the print-out of results, the square of the correlation coefficient is labeled “Multiple R-squared”.  

 

  1. Explain in terms specific to this analysis (i.e., not just general terms) what this R-squared tells us.

 

Response:ln_Income

Explanatory: Age

 

Residuals:

     Min                  1Q             Median                 3Q                  Max 

-0.83978.      -0.28834      -0.05761            0.25615        1.09741 

 

Coefficients:

                         Estimate Std. Error       t value     Pr(>|t|)    

(Intercept)         9.680077   0.158362   61.13   < 2e-16 ***

samp_reg$Age 0.016778   0.003995    4.20     5.76e-05 ***

---

Residual standard error: 0.4012 on 101 degrees of freedom

Multiple R-squared:  0.1487, Adjusted R-squared:  0.1403 

F-statistic: 17.64 on 1 and 101 DF,  p-value: 5.763e-05
