A measure of the amount of variation in the observed values of the response variable not explained by the regression is the----. The mathematical abbreviation for it is----.

Short Answer

Expert verified

Error sum of square

SSE

Step by step solution

01

Given Information

To determine the blank in the given statement.

02

Explanation

The error sum of the square is a measure of the amount of squared deviation in the observed values of the response variable that is not explained by the regression. The incorrect sum of squares formula is as follows:

SSE=鈭�yi-yi^2

As a result, the error sum of the square is a measure of the degree of variance in the observed values of the response variable that is not explained by the regression. SSE is the mathematical abbreviation for it.
