The Weight component generates a report in HTML format that can easily be written to a text file. The main report is generated by the WeightEngine.Execute method. However, additional information (such as information about cases that do not belong in the weighting matrix) is added by the WeightEngine.Prepare method. You should therefore write the report to the text file twice, once after the call to WeightEngine.Prepare and once after the call to WeightEngine.Execute as shown in the Weighting.dms sample file. For more information, see Setting up weighting in a DMS file.

Here is an example of the report for a simple target weighting run based on equal targets of male and female respondents.

For each cell in the weighting matrix, the report shows:

In the example report above, the weighting was based on one variable that has only two categories and so the weighting matrix has only two cells. Here is another example of the report for a weighting matrix of gender by age and equal targets of respondents in each cell.

In this example, the weighting matrix has been specified in the order gender then age and the report gives the figures for the Male category of the gender variable first and then for the Female category of the gender variable.

If the variables had been specified in the reverse order (age then gender) as in the example in More on target weighting, the table of figures would be rotated.

In addition to this information for each cell in the weighting matrix, the Weight component also reports the following information about the weighting overall:
