 If data do not meet the conditions of classical statistical approaches, statistical inferences drawn from classical approaches would be, to different extent, influenced in negative direction and even erroneous conclusions would be drawn. 当医学研究数据不能满足经典统计分析方法所要求的条件时，统计推断的可靠性将会受到不同程度的削弱，甚至出现错误的分析结论。 短句来源 RESULTS: The multiple imputation method imputed missing values of the crossover design and generated valid statistical inferences. 结果 :多重填补的方法可用于交叉设计中缺失数据的填补并得出正确的统计推断 . 短句来源 Results The multiple imputation method can impute missing values of the crossover design and generate valid statistical inferences. 结果多重填补的方法可用于交叉设计中缺失数据的填补并得出正确的统计推断。 短句来源 “statistical inferences”译为未确定词的双语例句

我想查看译文中含有：的双语例句  statistical inferences
 It sequentially generates Monte Carlo samples from a proposal distribution, adjusted by a set of importance weight with respect to a target distribution, to facilitate statistical inferences on the characteristic (state) of the system. The samples are allocated to different time points, often allowing some replicates, and statistical inferences are then made about the concentration-time behavior of the test compound. Typically, statistical inferences on these models are performed by means of simple error structures placed on the deterministic analogs of the underlying stochastic processes. However, we have no easy access to patient charts, and we are lacking a method for cost-effective merging of clinical case histories to make them suitable for much-needed statistical inferences. The empirical analysis shows that the conditional distribution of film returns has infinite variance, and this invalidates statistical inferences from the often-applied least-squares regression model. 更多 The R×C contingency tables with ordered variables could be analysed using the loglinear model. The ordered variables could be assigned scores accoring to the orders and an "ordered interaction model" could be set up. From this model the likelihood equations could be established so as to find the maximum likelihood estimates (MLE) of the expected frequencies. Such equations could be solved by iterative procedure, the goodness of fit of the model could be obtained (generally using statistics X~2 and G), and the... The R×C contingency tables with ordered variables could be analysed using the loglinear model.

From this model the likelihood equations could be established so as to find the maximum likelihood estimates (MLE) of the expected frequencies. Such equations could be solved by iterative procedure, the goodness of fit of the model could be obtained (generally using statistics X~2 and G), and the statistical inference on the existence of ordered interaction between two variables could de made. This method could analyse the problems encountered in medical research which involve data with ordered categories. 含有序变量的R×C列联表可用对数线性模型来作分析,可给予有序变量每一等级一个分数,建立一个“有序交互作用”模型,据此模型可列出求期望频数的最大似然估计值(MLE)的似然方程,用迭代法可求得这些估计值,并由此求得该模型的拟合优度(一般用统计量X2和G),从而可对两变量间是否存在有序交互作用作出统计推断。以前对医学上常遇到的等级分类资料构成的列联表尚只能用一般的R×C表方法进行分析,现应用本方法可充分反映由序提供的信息。 The author reviewed two general methods of comparing two means and their background. Afterwards a new method called bootstrap was used for comparison of two means. Bootstrap confidence limits were used for statistical inference. Two examples were calculated. The simulation shows that the power of bootstrap method is uniformly higher than that of Student's t test and the separated t' test, Student's t test having the lowest power under the condition of heteroscodastitity. 作者在复述两均数比较一般方法的基础上,给出了两均数比较的bootstrap法的基本思想及检验过程.实例演算了bootstrap法检验结果.并用Monte-Carlo法比较了t检验、t’检验和bootstrap法的检验功效.结果显示,在方差不齐时,后者的功效均高于t检验及t’检验,而t检验的功效最低. In order to ensure the correct use of the hypothesis testing in the statistical inference of enumeration data, this paper analyses by example the common statistica mistakes in the hypothesis testing of enumeration data.
