Chapter 5.1 Two Creations
Thus, in Satan’s hands, the first creation has become the old creation, and
God’s primary concern is now no longer with that but with a second and new
creation. He is bringing in a new creation, a new kingdom and a new world,
and nothing of the old creation, the old kingdom or the old world can be
transferred to the new. It is a question now of these two rival realms, and
of which realm we belong to.

chapter 9.3 Christ The End Of The Law
In Romans 6 we saw how God delivered us from sin; in Romans 7 we see how He
delivers us from the Law. In chapter 6 we were shown the way of deliverance
from sin in the picture of a master and his slave; in chapter 7 we are shown
the way of deliverance from the Law in the picture of two husbands and a
wife. The relation between sin and the sinner is that of master to slave;
the relation between the Law and the sinner is that of husband to wife.

3:21 The phrase But now (NuniV deV, nuni de) is extremely significant in Rom

Micah 7:6 refers to rebellion that happened during King Ahaz’s reign. It

不可能.
因为不同的A1,A2,
A1,B
A2,B
可能生成同样一个rho
除非你事先知道A的范围或者分布.
或者知道更高阶的或者更多的统计量.
例如A(k-1),B(k)的cor,等等.
简单的说,这就是个几个未知数几个方程的问题.
例如A是高斯分布,那么如果要知道A的分布,则需要两个方程.
那么一个cor是反推不回去的.

假如有两个时间序列A,B. 之间的correlation为rho(假设rho比较大),有没有什么办
法将A表
示成为一个B和rho的函数?A=f(B,rho).不要求数学意义上相等,数值意义上近似即可

我觉得楼主头脑里面一团浆糊,对多维随机变量非常不理解。题目都没提对。已经有
multi uniform distribution了,画图就行了,假设二维,则分布是一个水平面。
现在楼主又说“假设这两个uniform都是0,1的,cor为0.5”,那么这个joint
distribution不是uniform的,称之为multi uniform distribution又不对。
或者楼主想从两个uniform分布,以及他们的cor来推出joint分布?可惜这样的分布是
推不出来的。

LZ这个问题是这样的:
1、就像LS所说,已知两个marginal是不能保证joint的形式的:也就是说marginal都为
某一分布,joint不一定是相应的高维分布,即便normal也不行。
2、具体到你这个问题,真实的joint有无穷多钟选择。所以你的joint pdf也就是f(x,y
)只需要满足在[0,1]*[0,1]非负;f(x,y)对某一分量[0,1]积分后作为另一分量的函数
在[0,1]上恒为1;并且x*y*f(x,y)在[0,1]*[0,1]上积分值使得cor=0.5即可。
3、我给你提供一组例子,为了方便可以直接考虑(-1,1)上的uniform变量,因为线性变
换不改变correlation,在[-1,1]*[-1,1]上定义pdf:
f(x,y)=1/4+c*[sign(xy)*|xy|^(1/k)],
这里取c=(2k+1)^2/(24k^2),k>=3.由对称性你可以验证f(x,y)满足所有要求,并且参
数c和k的关系使得E(XY)=1/6也就是cor=0.5,但是显然k可以是任意>=3的整数。所以你
不能确定实际的joint pdf从哪里来。

来自主题: DataSciences版 - 问个R的问题
"任取一个数据,找出和它最‘相似’的10个数据,"这个好办,用apply就可以,比如:
sort(apply(mtcars[-1, ], 1, function(x) cor(x, unlist(mtcars[1, ]))),
decreasing=TRUE)[1:10]
至于categorical的数据如何处理,需要自己定义一个cor 函数.

来自主题: _TheBooks版 - 好,圣经背景问题:哥林多
使徒行传中的哥林多,距离 Mummius 屠城已经快两百年了。哥林多在当时是一个什么样
的城市?什么样的社会结构,经济结构,政治结构,民族组成,和文化组成?教会当时
的情形如何?为何书信集里大量篇幅涉及哥林多,或者与之相关?(比如说罗马书在哥
林多写成?)
结合这些,问一句经文:
Cor.9:9: Thou shalt not muzzle the mouth of the ox that treadeth out the cor
n.
其对摩西律法的引用见:
Deut.25:4: Thou shalt not muzzle the ox when he treadeth out the corn.
