Homework Answers
A straight line satisfies the least- squares property if the sum of the squares of the residuals is the smallest sum possible.
The least squares criterion is a formula used to measure the accuracy of a straight line in depicting the data that was used to generate it. That is, the formula determines the line of best fit. The approach is also called the least squares regression
