the type of rat used, the kind of statistical analysis, and the

不可证明为错 = 伪科学
可证明为错,可以"证伪" = 真科学
下面我想列出几个定义,如有任何一个statement错误,请大家探讨:
1)
真科学定义:“全部的天鹅都是白色的”(定义a)
hypotheses:
因为真科学可证明为错,只要我能找到一只黑天鹅,上面的定义就是错的。所以上面的(定义a:“全部的天鹅都是白色的”)是真科学。
data:
我找到了一只黑天鹅,根据科学可伪证性,我现在要修改这个真科学定义了,现在更新的新的真科学定义为:“天鹅里面有黑天鹅和白天鹅”(定义b)
conclusion:
这样真科学完成了(定义a)到(定义b)的迭代。所以(定义a)和(定义b)都是真科学定义
, 其中(定义a)得到了扩展。就是说科学得到发展。
2)现在的问题是:
尝试探讨这个是真伪科学定义?“世界上有UFO”(定义c)
hypotheses:
我要证明上面一句话是错的,才能判定上面一句是真科学定义。
所以,我要找到例子来说明:世界上没有UFO,这样才能证明(定义c)是错的。
data:
我可以寻找例子、图片来逐一鉴定那样东西是不是UFO, 结果(当然 我这里也是假设)每一个东西都不是UF

其实不是一个传统的sequential testing problem,因为sample size是不变的。
假设我有p个null hypotheses要test with same data set, 并且有一个很自然的顺序去
一个一个test。如果我在某一步fail to reject the null,就不用再做下去了。我觉的

来自主题: Statistics版 - hypothesis testing question
Look at the following two hypotheses:
H0: p1>p2. Given 90% confidence, critical value is 1.28.
H0: p1=p2. Given 90% confidence, critical values are 1.64 & -1.64.
Now suppose I conduct both hypotheses using the same sample. The test
statistic = 1.35 (should be the same for both tests). So that means p1 is
statistically higher then p2 BUT p1 and p2 are not significantly different?
I am thinking if “higher”, then should be “different”. How do you think?

《纽约时报》:揭开西方精英对中国的五大误解

作为世界上最大国家的执政者,中国共产党持续执政已达62年之久。那么迄今为止,中
共的执政业绩到底如何呢?
众所周知,在1949年中共建政以前,由于战火肆虐,外敌横行,中国的国土四分五裂,
满目疮痍;人民普遍食不果腹,人均寿命仅为41岁。但在今天,中国已跻身世界第二大

Who Is Charlie? O.J. Simpson’s 'Lost Confession' Involves This
Mysterious Character
On Sunday night, Fox dredged up a case that's driven America wild for
decades. Nicole Brown Simpson and Ronald Goldman's murder trial may have
been decided over two decades ago, but people are still fascinated over her
husband's chilling hypothetical account of the crime. During Fox's
special, O.J. Simpson's hypothetical co... 阅读全帖

Whenever my boyfriend asks me what kind of porn I want to watch, I usually
say, "Two girls, one guy." Why? Because women turn me on. To be clear, I am
straight—but I've always found that watching two women in sexual situations
is pretty hot.
Turns out, I am not alone. A new study from the University of Essex that's
making waves has found that straight women ar... 阅读全帖

I have just posted a pre-print of a review written by @K_G_Andersen, @
edwardcholmes, Ian Lipkin & Bob Garry about some particular features in the
#SARSCov2 spike protein and what they tell us about the evolution and
emergence of #covid19 in humans.
We explicitly consider (and show the evidence against) 'non-natural'
hypotheses for the origin.
Key points are that it _is_ well suited to human infection but not in the
way someone would have predicted using current computational models.

《纽约时报》:揭开西方精英对中国的五大误解
字号:小 大 2011-10-19 18:10 作者:李世默 来源: 四月网 我要评论(1) 分享到
作为世界上最大国家的执政者,中国共产党持续执政已达62年之久。那么迄今为止,中
共的执政业绩到底如何呢?
众所周知,在1949年中共建政以前,由于战火肆虐,外敌横行,中国的国土四分五裂,
满目疮痍;人民普遍食不果腹,人均寿命仅为41岁。但在今天,中国已跻身世界第二大
经济体,成为在全球有重要影响的大国;人民生活迅速改善,人均寿命已达74岁。
但问题还不至于此,对于中共的执政地位,西方的政治和知识精英即使不是直接否定,
也难掩其不快之意。这自然有其原因,在在西方媒体对中国的叙述中,有五大误解流传
甚广,甚嚣一时。以真相揭穿这些误解,已是刻不容缓。
误解一:由于没有选举,中共的执政地位没有得到其治下人民的认可。根据皮尤研究中
心的报告,中国政府享有高度支持,支持率在世界各国中十分靠前;2010年间,中国民
众对国家未来方向的满意度高达87%,这一数字近年来一直保持在80%以上;有66%的民
众相信,未来五年生活会继续改善;有 74%,也即绝大多数... 阅读全帖

Air Force downplays chance that pilot stole jet
Attack plane vanished nearly a week ago
April 8, 1997

WASHINGTON (CNN) -- The mystery deepened Tuesday as Air Force search planes
combed the Colorado Rockies for a missing A-10 attack plane, which
disappeared without a trace while on a training run nearly a week ago.
But while the Air Force has been exploring several possible theories about
what happened to the plane, officials are downplaying speculation that the
pilot, Capt. Craig Button, may h... 阅读全帖

Where Reid's Money Came From
By Daxton Brown
d*********[email protected]
In the Sharron Angle vs Reid debate on October 14th, Angle asked Senator
Reid how he was able to accumulate so much wealth on a politicians salary.
One would suppose that Senate Majority Leader Harry Reid is a fairly
important person and many in the media would already have answers to this
question. However, other than... 阅读全帖
