Abstract
We investigate the effect of power transformation of raw scores on the responsiveness of quality of life survey. The procedure maximizes the paired t-test value on the power transformed data to obtain an optimal power range. The parallel between the Box-Cox transformation is also investigated for the quality of life data.
摘要
我们研究原始分数的幂变换对生活质量调查响应性的影响。该程序在幂变换后的数据上最大化配对t检验值，以获得最佳幂范围。还针对生活质量数据研究了Box-Cox变换之间的相似性。
