本文提出一種非虛假設比倒按驗。方法為以非虛假設取代虛假設將經典單樣本，兩樣本，和多樣本比例檢驗加以擴展，並推導所需樣本量及功效函數。用Monte Carlo方法展示其行為。本文所提之檢驗計算簡便，當最小臨床承認差量取零時還原為對應經典檢驗，其觀測功效與期望功效吻合。本文所提之檢驗可用於以治療–對照差臨床意義或生物等效性研究為目的的臨床試驗。附有工作實例描述過程。

A test of non-null hypothesis on proportion is proposed. It is derived from the classical one-, two- and multi-sample test on binomial proportion using the non-null hypothesis in place of the null hypothesis. The required sample size and power function are obtained by the same way. Its performance was demonstrated through simulation. It is quite simple in calculation. It reduces to its classical counterpart when the minimal clinically relevant difference equals zero. Its observed power coincides with the prescribed power. The test is appropriate with the clinical trials for the clinical significance of treatment-control difference or bio-equivalence. A worked example illustrates the methodology.
