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. Independence of … See more 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 … See more When reporting your results, include the estimated effect (i.e. the regression coefficient), standard error of the estimate, and the p value.
