Each randomly-selected TE occurrence was weighted by the inverse of its probability of selection. For example, a respondent who reported three TE types and two occurrences of the randomly selected type would receive a TE weight of 6.0. The product of the Part II weight with the TE weight was used in our analyses, yielding a sample representative of all lifetime TEs occurring to all respondents. The sum of the consolidated weights across these respondents was standardized within each country to the observed number of respondents with the randomly selected disaster for purposes of pooled cross-national analysis.
