发信站: BBS 未名空间站 (Tue Oct 6 12:00:14 2009, 美东)
I bought a thinkpad X200 from a Lenovo agent. In the quote from him, I
could see "Bluetooth Spacer", but after I received this laptop, apparently
this computer does not have Bluetooth device. Then what is the difference
between Bluetooth Spacer and Bluetooth device? Thank you! |

发帖数: 6806 | 5 i have to correct you about difference between
new Widget
and
new Widget()
although they are really really subtle.
if type Widget is non-POD type, these 2 expressions are the same.
if type Widget is POD type, the first form will leave the new object at
indeterminate state, while the second form will still do default-
initialization, which means all-zero init for POD type.
I agree this difference is completely artificial and mostly can not be
derived from other things. |

XML is a markup language, it is a superset of HTML,
main difference between XML and HTML is, XML can keep
semantic information, so a XML file can be used by
different applications.
XSL is used to transfer XML to HTML or any other markup
language)by pattern matching.
This is my understanding. |

So you want to know just how and why these polymers, these macromolecules, act
differently from small molecules. So we'll tell you. That's just the kind of
nice people we are. There are, for those of you who didn't bother to read the
title, three ways in which polymers will act differently from small molecules.
And the reasons are a little bit more complicated than just "because they're
bigger". The three are usually named:

i don't think doing observations should be a problem, they understand you
need to have experience for your decision, and you can be very honest and
open about this, no point to hide.
but applying two different specialty residency programs in one hospital is a
different story, it almost always has negative impact.

发帖数: 179 | 20 suppose I have two groups(A,B) measuring the stock price with the same unit.
and I have a data point A1 in group A and a data point B1 in group B. The
distributions of group A and B are not known and are different.
Is there any way I can compare which point deviates larger from its group
center(mean or median)?
Assume there is no outlier, we can use (A1-mean_A)/(standard_deviation_A) .
But, I don't think we can compare the # for A1 and B1 since they are from
different distribution, can we?

发帖数: 258 | 25 The difference is minor. That's why in real applications, logistic is
dominent, except some econometricians would choose probit, which I don't
understand.
For multinomial case, things become different. The probit setting is more
flexible, but its estimation is much more time consuming. This is the reason
why you still don't see many real applications are done with probit. |
