7. 第七章 Combining and transforming random variables 结合转变随机变量:这一章节的内容主要师怎么把随机变量整合在一起,内容比较简单,通过练习题熟练一些公式就好了。 8. 第八章 Normal distribution and understand tables :是不是很熟悉,跟第二章节不同,我们需要能读懂正态分布的图表。比如什么事Z-score,什么...
If knowing whether any event involving X alone has occurred tells us nothing about the occurrence of any event involving Y alone, and vice versa, then X and Y are independent random variables. That is, there is no association between the values of one variable and the values of the other....
Random: 一般需要证明10% condition:n≤1/10 N(他也是需要standard deviation计算的条件)Large Counts : Proportion 需要的条件:np 和 n(1-p)需要至少是10.Large Sample: mean 需要的条件 sample size大于等于30时,无论population如何都可以满足normal的条件。如果不确定的话,同学们就需要自己作图来证明normal了。

The following items are related to the likelihood distribution, explanatory variables (fixed or random effects), spatial effects and the family likelihood hyperparameter. Finally, we have the Advanced INLA configuration, in which the user can specify: the INLA approximation strategy, the INLA integra...
MI is symmetric and non-negative and is equal to zero if and only if two random variables are independent, and higher values mean higher dependency. In MI, the feature gives non-zero value if it is relevant in correct classification. From Fig. 6, we have observed that most of the ...
