Introduction to "The Java Language Specification, Java SE 8 Edition"
By James Gosling, Gilad Bracha, Alex Buckley, Bill Joy, Guy L. Steele

The Java® programming language is a general-purpose, concurrent, class-
based, object-oriented language. It is designed to be simple enough that
many programmers can achieve fluency in the language. The Java programming
language is related to C and C++ but is organized rather dif... 阅读全帖 |

发帖数: 571 | 6 说你文化水平低，你就不知道收敛一点儿？
再给你扫个盲，“人均预期寿命”是指人出生时平均可存活的年数。是向前预期的。
1950年的人均预期寿命是指向1950年以后的，这和1949年前的内战没关系了。
就算把1950年后阵亡人数最多的朝鲜战争算上，由于战场不在中国，以中国的人口基数来看，这样的阵亡人数（就算为百万数量级）也不足以使人均预期寿命发生很多变化。
不过这需要统计学知识，我对你能否理解表示怀疑
Life expectancy is the expected (in the statistical sense) number of years
of life remaining at a given age.[1] It is denoted by ex, which means the
average number of subsequent years of life for someone now aged x, according
to a particular mortality experience. (In technical literature, this symb... 阅读全帖 |

某人k要么100%是孔子直系男孙，要么100%不是。
不可能90%是孔子直系男孙。
至于确定的方法，如果真要调查，并不难。
只需把所有族谱有记载，且还存活的男性取样品
测Y染色体上主要markers的DNA
再随机从人群（\notin K）中取数百至数千人的样品
以之为Null distribution
看看K的pair-wise similarities和Null的比
即可
若孔府男性子孙 的祖上很多是出墙生的
则其pair-wise similarities 必然相当diverse
和Null无异
否则，必然相互之间的similarity相当高
这个做法是基于100代人之内，Y染色体的变化不大的假设 |
