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 prediction doesn’t change significantly across the values of the independent variable. 2. … 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 looks like this: This output table first … Se mer When reporting your results, include the estimated effect (i.e. the regression coefficient), standard error of the estimate, and the p value. You … Se mer No! We often say that regression models can be used to predict the value of the dependent variable at certain values of the independent variable. … Se mer NettetA simple linear regression equation for this would be \ (\hat {Price} = b_0 + b_1 * Mileage\). We are dealing with a more complicated example in this case though. We …
