NettetLinearity means that the predictor variables in the regression have a straight-line relationship with the outcome variable. If your residuals are normally distributed and homoscedastic, you do not have to worry about linearity. Multicollinearity refers to when your predictor variables are highly correlated with each other. fanduel hacksNettet8. sep. 2024 · In statistics, linear regression is a linear approach to modelling the relationship between a dependent variable and one or more independent variables. In the case of one independent variable it is called simple linear regression. For more than one independent variable, the process is called mulitple linear regression. fanduel free 50
