Question

the set of equations obtained in the process of least square estimation​

Answer 1

$\huge\bold{\underline\purple{Answer}}$

An analyst using the least squares method will generate a line of best fit that explains the potential relationship between independent and dependent variables. ... These designations will form the equation for the line of best fit, which is determined from the least squares method.

Answer 2

$\huge\sf{Answer}$

The least squares method is a statistical procedure to find the best fit for a set of data points by minimizing the sum of the offsets or residuals of points from the plotted curve. Least squares regression is used to predict the behavior of dependent variables.10
