NettetThe simple linear regression equation we will use is written below. The constant is the y-intercept (𝜷0), or where the regression line will start on the y-axis.The beta coefficient (𝜷1) is the slope and describes the relationship between the independent variable and the dependent variable.The coefficient can be positive or negative and is the degree of …
Nettet26. okt. 2024 · Simple linear regression is a technique that we can use to understand the relationship between a single explanatory variable and a single response variable. This technique finds a line that best “fits” the data and takes on the following form: ŷ = b0 + b1x. where: ŷ: The estimated response value. b0: The intercept of the regression line.

The x-axis on this plot shows the actual values for the predictor variable points and the y-axis shows the residual for that value. Since the residuals appear to be randomly scattered around zero, this is an indication that heteroscedasticity is not a problem with the predictor variable.
