The linear regression equation is perhaps one of the most recognizable in statistics. It can be used to represent any straight line drawn on a plot: Where ŷ (read as “y-hat”) is the expected values of ...

Regression Equation . ... Linear regression attempts to estimate a line that best fits the data (a line of best fit) and the equation of that line results in the regression equation.

Multiple linear regression uses two or more independent variables to predict a dependent variable. The result is an equation you can use to estimate future outcomes based on known data.

This means, "Add the regression line determined by the model named mymodel to the current graph." The regression line is a visual interpretation of the prediction equation. The regression line is the ...

We will cover the computation of the regression equation and the analysis of variance table. We will also discuss S, R-Sq, R-Sq (adj), predicted values, confidence intervals, prediction intervals, and ...
