How to Use Frequency Weights in Displayr

In most situations, when people refer to weights, they are referring to sampling weights. By default, Displayr assumes that any weight is a sampling weight designed to correct for representativeness issues in a sample (e.g., to correct for an over- or under-representation of women in the sample).

However, it is possible to scale the sampling weight so that it can be analyzed using software that is designed for a frequency weight. For example, if a study has a sample size of 300, an average weight of 1.3, and an effective sample size of 120, then each weight is multiplied by 120 / (1.3 * 300). The resulting weight, which can be referred to as the calibrated weight, is then treated as a frequency weight.

In this situation, statistical inference is conducted under the assumption that the weights are frequency weights where the frequency weights are the supplied weights normalized to have an average value of 1 and then divided by the supplied extra design effect.

Requirements

A weight variable set up as a frequency weight

Method

Select the table for which you want to modify the weight.
From Properties , go to Appearance > Appearance > Significance > Advanced.
On the Significance Levels tab, change the Weights and significance setting to deff = 1.
Click Apply to Selection to apply the updated settings.
