First, giving increased weight to information in the title and index terms is likely to improve performance; we were not able to do this through meta-data weightings.
Estimated growth parameters were not highly sensitive to assumed mortality rates but changing the data-weighting scheme can result in differences in estimated growth parameters.
For questionnaire data, calibration weightings have been calculated., The weightings were produced by Statistics Sweden with the help of information from registers of the total population.
New methods can assist with correlation of input data layers, subjective weightings, and mixing of qualitative and quantitative data.
However, we can state something on that matter regarding the second period, as we are able to compare the figures of the years 1992 and 2014 chronologically speaking, they are the first year and the most recent one, respectively, for which there are CPI weightings data available.41.41
Age-standardized rates for incidence and mortality in our study are not comparable with other published data as different weightings were used.
Reweighting methods, involving the selection of data for up-weighting, can magnify errors in the intensity measurements, so that values of x can be precise but inaccurate.
The conventionally applied k3-weighting of the data was compared to k1-weighting and weighting by the inverse of the statistical error in the refinement of the structural parameters of PtO2.
Data were provided with weightings for household size and analyses were carried out on weighted and unweighted data, but as there were no substantial differences in results, we present the unweighted results.
However, it did not adjust for the fact that different smoking cessation advertisements used in New Zealand appear to have different effects on calls to the Quitline [ 4, 5] and that there was variable use of the higher impact advertisements over the time period studied (but we did not have precise enough data to undertake advertisement weightings).
