Web2 apr. 2024 · To get heteroskadastic-robust standard errors in R–and to replicate the standard errors as they appear in Stata–is a bit more work. First, we estimate the model and then we use vcovHC()from the {sandwich}package, along with coeftest()from {lmtest}to calculate and display the robust standard errors. A quick example: WebPCR, cf. [36], has been precisely designed to address such a setting. Using all observed covariates, PCR first finds an r˝pdimensional representation for each feature using the method of Principal Component Analysis (PCA); specifically, PCA projects every covariate A i; onto the subspace
