To avoid the heteroscedasticity of the independent variable influencing the results, we used robust standard errors.
We used robust standard error estimation adjusting for state level clustering.
Then, they used robust alignment algorithm to choose the best subset of matched points against incorrect matches and multiple matches.
The simplest and the most commonly used robust time-frequency representation is the robust short-time Fourier transform (STFT).
In addition, Jotshi et al. (2009) used robust optimization to schedule routes for vehicles after the disaster.
The suspect is said to have used robust technology to disguise his voice and conceal the source of the threats. .

As above, we used robust standard errors and individual fixed effects.
It used robust and clinically relevant outcomes.
Overall, the study used robust methodology.
Twenty-four of the 31 studies (77%) used robust questionnaires.
