Least squares fitted line
Nettet11. apr. 2024 · The Least Squares Regression Line is the line that makes the vertical distance from the data points to the regression line as small as possible. It’s called a “least squares” because the best line of fit is one that minimizes the variance (the sum of squares of the errors). A quite common model is the straight line model, which is used … NettetLeast square method is the process of finding a regression line or best-fitted line for any data set that is described by an equation. This method requires reducing the sum of the …
