Statistical techniques , including multi - regression , cluster analysis , and discriminant analysis , were employed to test ten null hypotheses 本研究以世界银行发展报告书的统计为依据,共选定1970年、 1975年、 1980年、 1985年、 1990年、 1995年各国高等教育在学率为分析资料。
The a - level is the probability of rejecting the null hypothesis when the null hypothesis is really true , that is , finding a significant association when one does not really exist 水平,是当0假设为真时拒绝0假设的概率,即,在某事件并非真的成立时所找出的有意关联。
The likelihood ratio tests indicate the null hypothesis of exact linear aggregations and identical preferences across income groups are rejected by the sample data 检定统计量概似比值显示样本资料拒绝需求模式设定?线性加总,和不同所得组别需求偏好结构是一致之虚无假说。
Fourth , despite these high costs , the time has passed that policy makers should still be acting on the null hypothesis that global warming will not occur 第四,尽管代价巨大,但是已经到了决策者们必须下定决心的时候了,而不应该仍然不断重复着“全球变暖不会发生”这种无谓的假设。
The limiting distribution of the test under null hypothesis is obtained . the number of change points can be estimated via the test procedure . we showed that the estimator is consistent 在原假设下得到检验统计量的极限分布;在假设检验过程中得到变点个数与变点位置的估计,并证明估计的一致性。
The practice of science involves formulating and finding hypotheses, statements that are capable of being proven false using a test of observed data. The null hypothesis typically corresponds to a general or default position.
