各位小蟲子,這樣的comment怎么回答?

|
日前收到一篇SCI期刊的審稿意見,要修改問題不是很多,主編給了大修。 其中有一個(gè)comment比較棘手,請(qǐng)問大家該怎么回答比較好。窟@種情況需要補(bǔ)數(shù)據(jù)嗎? 要是在不容易補(bǔ)數(shù)據(jù)的情況下,又該怎么回答這個(gè)問題。 The number of tests for each configuration is only 2. How the standard deviation and CoV can be obtained based on 2 samples? And how much is the accuracy of such numbers? 歡迎大家積極發(fā)言。 [ Last edited by googleuboy on 2013-2-27 at 19:40 ] |

這個(gè)回答很狡猾。但是如果同一個(gè)實(shí)驗(yàn)重復(fù)兩遍而有了不同結(jié)果,你要怎么確定哪一個(gè)更準(zhǔn)確?cov其實(shí)就是一個(gè)趨勢(shì),整個(gè)實(shí)驗(yàn)做下來一定次數(shù),當(dāng)每一個(gè)實(shí)驗(yàn)都與最標(biāo)準(zhǔn)的結(jié)果相差不大時(shí),這個(gè)cov就會(huì)顯示這個(gè)趨勢(shì)。樣本太少時(shí)是無(wú)法作為依據(jù)的。你說的解決方法很可能和lz初衷不一樣。如果按照你的解釋lz可能需要重新計(jì)算,得出不一樣的結(jié)果。 兩個(gè)數(shù)據(jù)是無(wú)法說明一個(gè)實(shí)驗(yàn)成功與否的。 [ 發(fā)自手機(jī)版 http://www.gaoyang168.com/3g ] |

對(duì)樓主的問題不是很了解,不知道是否做過DoE? 也許可以這么回答: The number of tests for each configuration is only 2. How the standard deviation and CoV can be obtained based on 2 samples? Re: Even though the number of tests for each configuration is only 2, there are N configurations and therefore the total number of tests are 2N. The standard deviation and CoV were based on all the tests. |
