팔할 선생께 코호트 연구 개념을 마케팅 개념에 적용할까 고민하고 있는데, 어떤 건지 지도해 주시면 감사하겠음. 검색을 하니 퍼널/코호트/.버킷테스트로 나오는 데...재미있는 보고서나 아! 이런 것도 있구나! 하며 누구나 알아 먹을 사례나 이야기를 들려 주면 좋겠음. 아래는 위키 영문판 내용 복사임 A cohort study or panel study is a quasi-experiment in the form of a longitudinal study (generally a type of observational study) used in medicine, nursing, psychology, social science, actuarial science, business analytics, and ecology. In a cohort study there is a passive follow-up of a group of people and a documentation of relevant characteristics or events related to this group of people. For instance in medicine, it is an analysis of risk factors and follows a group of people who do not have the disease, and uses correlations to determine the absolute risk of subject contraction. It is one type of clinical study design and should be compared with a cross-sectional study. Cohort studies are largely about the life histories of segments of populations, and the individual people who constitute these segments.
