| Video Discription | If you run a linear regression in R, then you have to check regression assumptions. One assmuption is the homoscedasticity assumption, i.e., that you have equal variances. For many linear regression assumptions in R, there are several testing strategies. For the homoscedasticity assumption, there are at least two options: 1. Looking at a scatter plot (predicted values and residuals) 2. Running the Breusch-Pagan test (one of many tests for heteroscedasticity) Used package: olsrr Used functions: For the plot: ols_plot_resid_fit() For the Breusch-Pagan test: ols_test_breusch_pagan() k_oDaBeIaz4 |
