WebNov 29, 2024 · I like robustness checks that act as a sort of internal replication (i.e. keeping the data set fixed). So if it is an experiment, the result should be robust to different ways of measuring the same thing (i.e. measures one should expect to be positively or negatively correlated with the underlying construct you claim to be measuring).

From the literature, two practical considerations arise. First, taking sample size on its own as a criterion is not enough to obtain accurate standard errors in the presence of heteroskedasticity. What matters is the number of observations per regressor. difference between mirrored and flash lenses
