WIP CVM calibration for updated CVS weights: (1) 2022 establishments control was updated based on new CBP and EDD data (2) Outlier analysis and detection was updated using bootstrap method (as opposed to normal distribution assumption) (3) Outlier values were winsorized based on the thresholds determined above using bootstrap method to build confidence intervals (4) Finally, a truck utilization factor of 90% was assumed (as opposed to the previous 100% assumption) As a result, CV calibration targets changed significantly.
