Q. 9
Question
9. Based on the least-squares criterion, the line that best fits a set of data points is the one with the ________possible sum of squared errors.
Step-by-Step Solution
Verified Answer
Based on the least-squares criterion, the line that best fits a set of data points is the one with the smallest possible sum of squared errors.
1Step 1: Concept Introduction
Least-squares criterion:
The line that best fits a set of data points with the minimum sum of squared error is known as the least-squares criteria.
2Step 2: Explanation
If the sum of squared errors is the smallest feasible, the line is the best fit for a collection of data.
As a result, the line that best fits a set of data points is the one with the smallest possible sum of squared errors, according to the least-squares criterion.
