WebbPrevious; Next; In the application to the two 2016 FHWAR surveys, we used raking rather than regression estimation for calibration. As for regression estimation, the goal is to create new raking controls for each of the replicates, so that the replicate variance estimator for the primary survey accounts for the variability of the control totals from the … Webb3 apr. 2024 · We distinguish two kinds of Ranking Losses for two differents setups: When we use pairs of training data points or triplets of training data points.

It's important to remember color accuracy differs from monitor to monitor, even if they're the same model because of manufacturing differences, so the results on our unit might not be the same as yours.
