Heteroskedasticity-consistent standard errors areused to allow the fitting of a model that does contain heteroskedastic residuals. The first such approach was proposed by Huber (1967), and further improved procedures have been produced since for cross-sectional data, time-series data and GARCH estimati...

It is widely accepted that the Poisson pseudo log-likelihood problem is the adequate econometric implementation to the similar gravity equation. It accepts zero values that are common in the trade matrix and behaves well in the presence of heteroskedasticity (higher variance for smaller flows). It ...
Then, the weighted model is again subjected to least squares estimation to achieve correction for heteroskedasticity and correlation. The results presented in Table 4 indicate that the benchmark results are robust. Table 4. Replacement of estimation method. 4.3.2. Elimination of Extreme Values ...
