WebCluster-robust standard errors for many different kinds of regression objects in R can be obtained using the vcovCL or vcovBS functions from the sandwich package ( link ). To perform statistical inference, we combine these with … WebThis test shows that we can reject the null that the variance of the residuals is constant, thus heteroskedacity is present. To get the correct standard errors, we can use the vcovHC () function from the {sandwich} package (hence the choice for the header picture of this post):
