发帖数: 490 | 1 对于一个missing number的题目，用xor是最好解法
比如，1，2，3，5，missing number is 4
(0^1^2^3^4^5) ^ (1^2^3^5) = 4
xor 1-n的数，再xor array里面的数给你那个唯一的missing number
但是这招对于2个或以上missing number行不通
所以我们回到addition to find missing number的路上来
sum(1-n) - sum(elements in array) 也可以给你唯一的missing number (potential
overflow problem)
把那个方法generalize到>1个missing number
a1=sum(1-n) - sum(elements in array), a1是missing number的和
a2=sum(1 squre-n squre) - sum (elements squre in array)， a2是missing number
的平方和
假设两个missing number是x, y
x+y=a1

发帖数: 5138 | 2 我不想和你绕弯子。我的例子和问题如下：
“假设100个被抽样的个体有10个在被测变量上发生missing，你是愿意用90个个体的均数
去取代那10个missing values然后再计算一个均数? 还是直接使用90个个体计算出来的
均数？假设这是一个单变量情形，且被测变量是连续型的。”
按照基本数据信息，我们确实没有关于missing pattern的信息，从而也就无法对
missing values进行弥补，也就只能用那90个数据的统计量作为最终结果。
再说到missing patterns，或许在多变量条件下有可能获得关于它们的一定程度的认识。
但请别忘了，如果那些values不是missed的话，data patterns可能是另外的表现形式。
其实，我在关于本LZ的第一个回帖中已经清楚地展示了missing values的性质：
a MISSING value = an UNKNOWN value

Global mean/median does not work well. However you can try group mean/median

This is a really good way. You don't think it is useful just because you
have never used/tried it. Sometimes missing value makes lots of business

本以为只要输入车牌，就能看到miss掉几个，付掉就行了。谁知道必须时间要精确到每
15分钟，地点也要说明，不然就得按maximum付。问题是当时光顾着开车了，都不记得
miss掉哪几个了。每个时间输入进去，都能看到miss掉的记录，这不是坑人吗？难不成
为了以防万一，每个时间每个路段都要付一个啊？直接输入车牌显示一下有这么难吗？
这么做纯粹是为骗钱吧？要么多付了，要不少付了收到高额罚单。
唉，大家都有什么好办法啊？ |

第一次来这个版，因为Miss Fish来自这个州。
Miss Fish就是在我回国后3个月，飞到MA和我老公共度几个春宵的mm。
相信她会看到这些话，因为他们两个是在未名交友上认识。
从此我痛恨未名交友，为北美的WSN们，提供一个寻找一夜情或者N夜情的交易场。
不明白为什么，网络几天的聊天，就可以飞过去，同床共枕，
国内的男女就算闷骚，也未至于此。
美国的生活是寂寞，是压抑，
压抑到一夜情似乎如麦当劳一样的方便利索，
方便到就算有老婆也无所谓，
最多不和他结婚。
打老公的电话，不接，
打她的电... 阅读全帖 |
