Case Selection via Matching
نویسنده
چکیده
This article shows how statistical matching methods can be used to select ‘‘most similar’’ cases for qualitative analysis. I first offer a methodological justification for research designs based on selecting most similar cases. I then discuss the applicability of existing matching methods to the task of selecting most similar cases and propose adaptations to meet the unique requirements of qualitative analysis. Through several applications, I show that matching methods have advantages over traditional selection in ‘‘most similar’’ case designs: They ensure that most similar cases are in fact most similar; they make scope conditions, assumptions, and measurement explicit; and they make case selection transparent and replicable.

متن کاملاستفاده از Propensity Score برای همسان سازی نمونه ها در یک مطالعه مورد شاهدی
Background and Aim: Case-Control studies provide evidence in the area of health. Validity and accuracy of such studies depend to a large extent on the similarity (similar distributions) of the case and control groups according to confounding variables. Matching is a method for controlling or eliminating the effects of important confounders. Matching using propensity score has recently been intr...
متن کاملExperimental confirmation that body size determines mate preference via phenotype matching in a stickleback species pair.
Mate choice by phenotype matching, whereby individuals prefer a mate whose phenotype is similar to their own, should facilitate speciation with gene flow. This is because the genes that control mate signal (the phenotype being matched) also determine the preferred mate signal ("mate preference"). Speciation is made even easier if phenotype matching is based on a trait under divergent natural se...

متن کاملPattern Matching via Choice Existential Quantifications in Imperative Languages
Selection statements – if-then-else, switch and try-catch – are commonly used in modern imperative programming languages. We propose another selection statement called a choice existentially quantified statement. This statement turns out to be quite useful for pattern matching among several merits. Examples will be provided for this statement. keywords: selection, pattern matching, choice quant...
