Calibration of weights in register-based surveys:compensating for missing values
![Page 4: Register-based statistics production Administrative data used for statistical purposes](https://reader036.fdocuments.net/reader036/viewer/2022062422/56812cef550346895d91b831/html5/thumbnails/4.jpg)
Two ways of handling missing values
• Based on the shaded columns in 7.10, giving weight 0 to persons with missing values
• Based on adjusted weights after calibration

Methods to correct for level shifts in time series
• Correcting for level shifts in time series is called linking time series. We differentiate between linking at macro level and linking at micro level.
• Linking at macro level has the disadvantage that it can be difficult to ensure consistency among several linked series, and there may be many of them.
• Linking at micro level does not have this disadvantage, since all possible time series are linked at the same time, and all these series will be consistent. Linking at micro level is carried out by calculating revised weights in data matrices for the years or periods that have been revised. The old time series values are given by the original weights, while the revised weights can be used to calculate the linked series.
