Effect sizes and power analysis can mitigate over-reliance on the p value, and offer researchers better informed preparation and interpretation on experiments. Many research fields now require authors to include effect sizes in NHST results, and this trend is expected to be more and more common. ...

如何确定假设检验的样本量(sample size)? 2019-12-11 22:26 − 在《如何计算假设检验的功效(power)和效应量(effect size)?》一文中,我们讲述了如何根据显著性水平α,效应量和样本容量n,计算功效,以及如何根据显著性水平α,功效和样本容量n,计算效应量。但这两个应用都属于事后检验,也就是说,就算假设检验之后...
这里的结论就和那片文献里的有点接近了,effect size表示从模型中删除指定的exogenous construct(外生构面)时R2值的变化——为了确定从结构模型中删除predictor construct(预测构面) 是否对endogenous construct(内生构面)有实质性影响。可以通过计算预测因子结构 在/不在 结构模型中的的R2值差异,确定解释力的差异。

How big a sample size do I need to test my hypotheses? How do I know if my study has enough statistical power? What’s wrong with post hoc power analyses? Can you recommend a good power calculator? Can you recommend a plain English introduction to power analysis?
