Services for data processing, linking and analysis

To help you fully exploit the analysis potential of your data, we offer various services for preparation, enrichment and weighting.

We also support you in analysing your data from complex sample surveys and in handling the challenge of non-response.

We check and correct labels, filters, inconsistencies and multiple answers in your survey data. The checked data can then be documented at study and variable level.

More information

On request, we link your data with context data (e.g. georeferenced data) and integrate several data sets, for example to create a time series or for international comparative projects.

We help you to calculate the probabilities of selection in the context of complex sample designs to determine design weighting. Furthermore, we support you in the calculation of so-called calibration or adjustment weighting to adjust sample biases caused by nonresponse.
