The Innovation Panel dataset is designed to be used with weights (see why you should use weights).
A number of different weights are provided to meet the different needs of users. The weight for your analysis reflects the survey instrument which is the source of the data, the analysis level (e.g. household or individual questionnaire) and the combination of waves involved.
All weights follow a naming convention, designed to help users to pick the correct weight. The name of each weight reflects the wave for which the weight is calculated, level of analysis, data source and its nature (design weight, cross-sectional analysis weight or longitudinal analysis weight). The rules are described in the Naming Conventions for Weighting Variables page.
If your analysis uses only data from one wave, select the _xw (cross-sectional) version of the weight. This weight is defined for all sample members[1] who responded to the relevant survey instrument at that wave. If your analysis uses data from two or more waves, select the _lw (longitudinal) version of the weight for the most recent wave included in your analysis. This weight is defined for sample members who responded to the relevant survey instrument at each wave.
For individual level analysis you may want to combine information from different questionnaire sources. In this situation please select the weight suitable for the lowest level according to the hierarchy below:
| Level of Analysis | Questions available for |
|---|---|
| 4 | Household level (all enumerated individuals) |
| 3 | Proxy and main adult interview |
| 2 | Main adult interview only (no proxy) |
| 1 | Self-completion interview, adult or youth |
Example
For example, if in one model you use wave 1 data from the adult main and proxy interview as well as from the self-completion, then the correct weight will be a_indscip_xw – the weight for the self-completion questionnaire as its level (1) is lower than the level for main and proxy interview (3).
