"Mean"
You, with your words like knives
And swords and weapons that you use against me
You have knocked me off my feet again
Got me feeling like I'm nothing
You, with your voice like nails on a chalkboard
Calling me out when I'm wounded
You picking on the weaker man
You can take me down with just one single blow
But you don't know, what you don't know...
Someday I'll be living in a big ol' city
And all you're ever gonna be is mean
Someday I'll be big enough so you can't hit me
And all you... 阅读全帖 |

The first half of the sentence is straightforward: when we are in a

发帖数: 1440 | 5 Talk About Life Meaning
We humans appear to be meaning-seeking creatures who have had the misfortune
of being thrown into a world devoid of intrinsic meaning. One of our major
tasks is to invent a meaning sturdy enough to support a life and to perform
the tricky maneuver of denying our personal authorship of this meaning. Thus
we conclude instead that it was “out
there” waiting for us. Our ongoing search for substantial meaning
systems often throws us into crises of meaning.

for Hamlet, to be or not to be is quite a dilemma: he was doomed to be

For example, if you would like to computer average score by gender, you can

will plot group means and confidence intervals.
(it requires gplot package)
2) aggregate(score, list(gender_class = gender), mean)

看来你是苦大仇深呀。其实每个杂志都有mean的时候。你说得这几本杂志我都有经历，

招风，大家对在MS上发文章的期待又比别的杂志高得多，所以很容易记住MS的mean。而
IJPE这类杂志因为量太多，被IJPE mean一下，无所谓，投别的就行了。

MLE: It is not hard to see the sufficient statistics are the 'mean' and the
'mean of log(data)'. The MLE for shape is accessible using Newton method.
Moment Method: Quite straightforward -> mean = shape*scale, var = shape*(
scale)^2.
However, truncated Gamma, if I get it, is much difficult even if you know
the interval [a,b] for truncation. The density function will have the form g

你这个问题我觉得很容易解释吧：max和min虽然指定了，但是max和min pixel的个数也
没有说，更别说中间其他value的个数了... 如果总共有十个pixel，9个value是1，1个
是10，mean也不会是5啊；或者说1个是1，9个是10，mean也不是5，同时也跟前面的
