4.85 A measure of the amount of variation in the observed values of the response variable explained by the regression is the-----. The mathematical abbreviation for it is----.

Short Answer

Expert verified

A measure of the amount of variation in the observed values of the response variable explained by the regression is the Regression Sum of a square.

The mathematical abbreviation for it is SSR

Step by step solution

01

Given Information

To determine the blank in the given statement.

02

Explanation

The regression sum of the square is a metric for calculating the amount of squared variance in the observed values of the response variable explained by the regression. The regression sum of squares formula is as follows:

SSR=∑yi^-y¯2

As a result, the regression sum of the square is a measure of the amount of variance in the observed values of the response variable explained by the regression. SSR is the mathematical abbreviation for it.
