查询词典 random choice

Throughout comparing the above estimating methods, we have the following results: the estimators of the moments of the errors does not depend on the random effects, and that of the random effects does not depend on the errors, and then the corresponding asymptotic variances are very simple and optimal; when the random effects are multivariate, we can not construct different estimating equations for the random effects and errors respectively, which results that the asymptotic covariances of estimation are very complex and then the estimating efficiency is bad.

比较上述两种估计法，我们发现：当随机效应是一维的时侯，误差的各阶矩的估计不依赖不可观测的随机效应，随机效应的估计也不依赖误差，因此，估计的渐近方差结构特别简单也是最优的；而当随机效应是多维的，因为随机效应的协变量的影响，我们没有办法针对随机效应和误差的各阶矩分别建立估计方程，这导致所得的估计的渐近方差或者协方差矩阵特别复杂，从而估计的效果不是很好。

Perhaps the giving up is the best choice, lets choice which oneself extricates; Let all become the tranquil choice; Let me return to the study choice, perhaps with is lets my happy choice

居民在城市的不同场所完成的上班、家务、娱乐、购物等活动以及场所间的空间移动构成了庞杂的城市活动系统的主体，其中在场所间的单向空间移动过程即为出行行为。

It is proved that the choice function must satisfy the axiom of consistency if the choice function meets the axiom of substitutability together with quotafilling condition; then, it is driven that the choice function is a path independence choice when it satisfies the substitutability and consistency condition.

When you are making the choice for the Voice for Truth , it does not appear to be a choice for That which You Are . But it is a choice for that which inescapably provides the experience of Integrity and Peace and invulnerability , which the choice for the ego and the dream never did provide—which gives you a clue that you are on the right track .

虽然选择真理之声看起来并不像是选择了你的真相，但这个选择必会让你体验到你里外一致的圆满、真实的平安、以及百害不侵的本质，这是选择小我与梦境絶对无法带来的效果，这样的经验会让你知道自己已经上道了。

There are two aims of the article: one is to trace the trajection of education and professional choice of those women doctors who were either migrant from China or bone locally and both worked in Taiwan in early 1950. Through the discussion of familiar influence on individual choice, it argues that individual choice is not real individual choice but a results of the constraint of cultural values, gender relations and educational and professional systems.

本文有二个目的，一是藉著追溯1950年代在台湾行医的台湾本地与中国移台女医师的教育与职业选择的过程，藉著讨论家庭影响个人所做的抉择，企图说明个人的教育与职业的选择其实不是个人的选择，而是受到当时的文化价值，性别关系，教育和职业制度的限制。

Meanwhile, important random acute angle principle、theorem of random full mapping and theorem of random one-one mapping are proved.

Then, both the stationary and non-stationary random response of hysteretic system with cubic rigidity and sticky damp were deduced and calculated. In the research of colored white noise, the filter for shaping the power spectral density was designed and the random state response of enlarged vector was gotten. With this, the experimental power spectral curve was changed into colored white noise and the random response could be easily calculated.
