In olsrr: Tools for Building OLS Regression Models

when fitted.values == TRUE, fitted values from the regression

are used for the test

Code
  ols_test_score(model)
Output

   Score Test for Heteroskedasticity
   ---------------------------------
   Ho: Variance is homogenous
   Ha: Variance is not homogenous

   Variables: fitted values of mpg

          Test Summary         
   ----------------------------

   Chi2          =    1.268973 
   Prob > Chi2   =    0.2599594

Code
  ols_test_score(model, rhs = TRUE)
