Let us consider **y _{est}** as the estimated value of

The above equation is called the

*Example:*

- The regression line of
**y**on**x**is given by the equation:**y = 35.82 + 0.476 x**The following table depicts the actual values of

**y**and the estimated values of**y**(denoted by y_{est}).x 65 63 67 64 y 68 66 68 65 y _{est}66.76 65.81 67.71 66.28 y - y _{est}1.24 0.19 0.29 -1.28

**Standard Error Estimate**for this problem we have the solution as follows.
