A linear line of best fit can be defined as a straight line providing the best approximation of a given set of data. What does line of best fit mean? Fitting a line by eye residuals;
The criteria for the best fit line is that the sum of the squared errors (sse) is minimized, that is, made as small as possible. We just need to find the values b0 and b1 that make the sum of the squared prediction errors the smallest it can be. Instead, the idea is to get a.
A line of best fit is a straight line that shows the relationship between two sets of data. Statisticians typically use the least squares method (sometimes known as ordinary least squares, or ols) to arrive at the geometric equation for the line, either through manual. Line of best fit.
