WebThe ESS data contains 3 types of weights: dweight: These are the so-called design weights. Quoting the ESS website: “the main purpose of the design weights is to correct for the fact that in some countries respondents have different probabilities to be part of the sample due to the sampling design used.” WebMost functions to fit multilevel and mixed effects models only allow to specify frequency weights, but not design (i.e. sampling or probability) weights, which should be used when analyzing complex samples and survey data. rescale_weights () implements an algorithm proposed by Asparouhov (2006) and Carle (2009) to rescale design weights in survey …
