Nettet13. okt. 2024 · For the same linear regression example, let us change the equation to y=B0 + B1x + e. Again, y is the dependent variable, and x is the independent or known variable. B0 is the constant or intercept, B1 is the slope of the regression coefficient, and e is the error of the estimate. Simple linear regression is a parametric test, meaning that it makes certain assumptions about the data. These assumptions are: 1. Homogeneity of variance (homoscedasticity): the size of the error in our … Se mer To view the results of the model, you can use the summary()function in R: This function takes the most important parameters from the linear model and puts them into a table, which … Se mer No!
