Precision calculations are calculated on the main variables broadcast (the quantities of waste by combined categories).
The precision indicators (coefficient of variation, 95% confidence interval) take into account errors due to sampling, total non-response correction and calibration, but not the error related to partial non-response correction.
The results of the calculations are in the file :

See the following file, which summarizes the differences betwenn the aggregate coming from the adjustment (including data cleaning) and the target variables.
