这种情况,按照以往的做法,一般会做一个小样本的预实验(pilot study)来预估效应量,但是这种做法是不靠谱的:When power analyses based on pilot data are biased: Inaccurate effect size estimators and follow-up bias。所以我推荐去努力从文献中寻找类似的研究,再根据这些研究来估计效应量会更有说明力。 情况四:...
Estimation of statistical power and sample size is a key aspect of experimental design. However, in metabolic phenotyping, there is currently no accepted approach for these tasks, in large part due to the unknown nature of the expected effect. In such hypothesis free science, neither the number...

Statistical power analysis characterizes the ability of a study to detect a meaningful effect size—for exam-ple, the difference between two population means. It also determines the sample size required to pro-vide a desired power for an effect of scientific interest. Proper planning reduces the ...

Power Analysis and Sample Size Determination for Crossover Trials with Application to Bioe
In conclusion, we provide a power analysis tool (http://www2.hawaii.edu/~lgarmire/RNASeqPowerCalculator.htm) that captures the dispersion in the data and can serve as a practical reference under the budget constraint of RNA-Seq experiments. 展开 关键词: RNA-Seq sample size power analysis ...
