Linear regression straight line
In statistics, simple linear regression is a linear regression model with a single explanatory variable. That is, it concerns two-dimensional sample points with one independent variable and one dependent variable (conventionally, the x and y coordinates in a Cartesian coordinate system) and finds a linear function (a non-vertical straight line) that, as accurately as possible, predicts the depende… Nettet28. nov. 2024 · The formula for drawing the “best fit line” when working with estimations will be the same as the straight line formula, but with hat notation.
