摘要
建立了百分回归分析理论。根据该理论，可以对百分位值和百分率进行分析、预测、控制和检验，可以在散点试验中考虑可靠度和置信度。文中还提出了组合回归函数的概念，从而可以充分利用以往数据和经验，提高预测和控制的精度。
A theory of percent regression analysis is established in this paper.Forecast inter-vals and control regions of population percentiles and percentages can be calculated,and func-tions of the percentiles and percentages may be tested by this theory.Thus reliability and confi-dence level can be considered when test point scattering.A method of combining regression func-tions and sample variances is also presented to make full use of previous data and raise the preci-sion of forecasts and controls.
