The Five Assumptions of Multiple Linear Regression
Multiple linear regression makes all of the same assumptions assimple linear regression: Homogeneity of variance (homoscedasticity): the size of the error in our prediction doesn’t change significantly across the values of the independent variable. Independence of observations: the observations in the dataset … See more To view the results of the model, you can use the summary()function: This function takes the most important parameters from the linear model and puts them into a … See more When reporting your results, include the estimated effect (i.e. the regression coefficient), the standard error of the estimate, and the p value. You should also interpret … See more Web5.7 - MLR Parameter Tests.
