[Sample Size Calcularion] [샘플 수 계산]
이 글의 단축 주소는
https://tinyurl.com/MY-sample-size 필요하다면 메모해두자.
[샘플 수 계산] 책이 절판되었다고 해서,
새로 써달라는 요청을 여러번 받았지만,
쓸까 말까 계속 생각 중입니다.
어떻게 하는지는 간단하지만, 그것이 무엇을 의미하는지, 왜 하는지를 설명하는 것은
좀더 베이직한 내용이 될 것같아서,
그리고, 막상 쓰려고 하니 귀찮은 생각도 들어서 그냥 망설이고 있습니다.
2021년이 되었으니 써야 하나 하는 생각도 들고...
책을 쓰기 전에 일단
그동안 내가 만들었던 샘플 수 계산의 도구들을 모두 모아보았습니다.
누군가는 필요할 것같아서 만들긴 했지만,
막상 쓰는 사람은 거의 없을 듯...
https://play39.shinyapps.io/Sample_Size/
그중에 처음 것 이것은 가장 많이 쓰이는 것이니, 일반인은 이것만 알아 두면 될 것같고,
나머지 것들은 정말 특수한 연구를 하시는 그분들만 필요한 것들임..
혹시 빠진 것이 있을지도 모르겠습니다. 잡다하게 흩으진 것을 그나마 한데 모아 보았지만..
만들 때는 한참 신나게 만들었지만, 지금은 잊혀진 장난감과도 같이 약간은 미안한 마음도 듭니다.
