The SPSS Complex Samples module procedures do not have something like the STDVAR option that exists in SUDAAN, but like SAS, SPSS can produce directly standardized estimates with appropriate standard errors.
WebNov 17, 2024 · Finally, to correct for heteroscedasticity and autocorrelation, we estimated the Prais–Winsten regression model, with standard errors corrected for heteroscedastic panels (models 5 and following). Once the most correct model was identified, we proceeded to run four models to identify the effect of immigration by gender and age (models 5–8).

The topic of heteroskedasticity-consistent (HC) standard errors arises in statistics and econometrics in the context of linear regression and time series analysis. These are also known as heteroskedasticity-robust standard errors (or simply robust standard errors), Eicker–Huber–White standard errors (also Huber–White … See more Heteroskedasticity-consistent standard errors are introduced by Friedhelm Eicker, and popularized in econometrics by Halbert White. See more If the regression errors $${\displaystyle \varepsilon _{i}}$$ are independent, but have distinct variances $${\displaystyle \sigma _{i}^{2}}$$, then $${\displaystyle \mathbf {\Sigma } =\operatorname {diag} (\sigma _{1}^{2},\ldots ,\sigma _{n}^{2})}$$ which can be … See more • Freedman, David A.
