FILTERTRACE: Stata module to trace filter or contingency questions
filtertrace is used to trace filter or contingency questions. In social research questionnaires often contain contingency questions, i.e. questions respondents are asked contingent on their answer to a previous filter question. filtertrace allows to detect (coding) errors in contingency questions in a two-step approach. In a first step filter questions are reconstructed. In a second step contingency questions are checked and errors are tagged.
