안녕하세요~교수님..통계결과 궁금한점이 있어서요...

Beauty 2016.08.22 14:01 Views : 433

자료 분석에서 치료결과에 따른 임상적, 일반적 특성의 차이를 x2로 검증하였다. 표4에 보면 기대빈도가 5미만인 셀들이 20%를 초과하는 경우에 대한 통계 분석이 어떻게 되었는지에 대한 설명이 없다.-> 이럴땐 어떻게 해야할까요?도와주셔요..

후향적 조사연구입니다.

질문2:

사망위험요인 분석에는 환자의 중등도 보정이 필요한데, 중등도를 조사했다는 언급은 있으나 중등도 조사결과는 표나 결과에서 제시되지 않았다. (지적사항)

후향적조사연구에서도 중등도 보정을 해야하나요?
