Nettet21. apr. 2024 · How to find the Linear Regression Equation? To find the least-squares regression line, we first need to find the linear regression equation. From high school, you probably remember the formula for fitting a line y = kx + d y = kx + d where k is the linear regression slope and d is the intercept. Nettet2. apr. 2024 · 12.7: Outliers. In some data sets, there are values ( observed data points) called outliers. Outliers are observed data points that are far from the least squares line. They have large "errors", where the "error" or residual is the vertical distance from the line to the point. Outliers need to be examined closely.
NettetThe criteria for the best fit line is that the sum of the squared errors (SSE) is minimized, that is, made as small as possible.
