1.
If zero is included in the 95%
CI, no significant systematic change in the
mean is present.
請問這個判斷基準是否缺乏重要姓,因為文獻說雖然TF20的CI沒有包含0,但因為CI 小且靠近0,又加ICC高,所以仍為reliable; 另不知此方法和t-test看兩分數之差異,哪方法比較prefer?
2.
Result 部分: TDPM would need to decrease between 10% (TE20) and 38% (TF20), and
increase between 17% (TF40) and 24% (TE40) in groups of uninjured subjects to
be 95% confident of detecting a real change.
還是無法理解,因為有了LoA,可知超過LoA就是real change,但現在要調整TDPM的分數是什麼意思呢,另外不知數據是從何而算 ?好像無法從資料推出?
3.
雖然文獻如此寫,但判斷 heteroscedasticity
僅用相關係數恰當嗎?
4. LoA怎樣算大怎樣算小是看多數人對於某個評估工具分數的界定? 是很主觀的?
