Last but not least, you can download a report of the results (in HTML) by clicking on the Download button, and you can choose whether you want to include the R code or not.
Note that although the assumptions are displayed, it is your responsibility to check them to assess the validity of the linear model. where y is the dependent variable, and x1, x2, are the independent variables.
and the assumptions to check the validity of the modelĪll formulas, steps and computations to arrive at the final results are also provided. the regression plot with some key measures. a and b are constants which are called the coefficients. The general mathematical equation for a linear regression is y ax + b Following is the description of the parameters used y is the response variable. the estimates \(\beta_0\), \(\beta_1\) and the regression model computed by hand A non-linear relationship where the exponent of any variable is not equal to 1 creates a curve. a recap of your dataset together with some appropriate descriptive statistics. In the results panel (on the right side or below depending on the size of your screen), you will see: Change the x and y-axis labels for the regression plot if needed. If you do not want to display the confidence interval around the regression line, uncheck the checkbox under Plot A simple linear regression (also known as a bivariate regression) is a linear equation describing the relationship between an explanatory variable and an. 
The x field corresponds to the independent variable, while the y field corresponds to the dependent variable
