About us

I am Xiaoxu LI, a statistical teacher at the department of psychology, Fudan University at Shanghai. My email is lixiaoxuAtGmail and lixiaoxuAtFudan.

Participants of my courses present our statistical practices here, in L^AT_EX supported by mimetex and RWeb powered by RwebFriend. The following entries are featured posts on our sites.

FAQ for registration:

  • If you have just a username without a site, login your account and then click http://fudan.lxxm.com/wp-signup.php to register a site for the username.

 
Use the following code to output  e^{2\pi i}=1 .

[tex] e^{2\pi i}=1 [/tex]

More demos of L^AT_EX :

X=\tau_{x}+\Lambda_{x}\xi+\delta
Y=\tau_{y}+\Lambda_{y}\eta+\epsilon

\eta=\alpha+B\eta+\Gamma\xi+\zeta

\delta\sim N\left(0,\Theta_{\delta}\right)
\epsilon\sim N\left(0,\Theta_{\epsilon}\right)
\zeta\sim N\left(0,\Psi\right)
\xi\sim N\left(\kappa,\Phi\right)

X=\left[\begin{array}{cccc}
x_{11} & x_{12} & \cdots & x_{1p}\\
x_{21} & x_{22} & \cdots & x_{2p}\\
\vdots & \vdots & \ddots & \vdots\\
x_{N1} & x_{N2} & \cdots & x_{Np}
\end{array}\right]

 

Use the following code to output Demo1 of Rweb. There are more executable online demos.

[rcode] example(princomp) [/rcode]

Demo1 of RWeb:



Demo2 of RWeb:



Demo3 of RWeb: Upload a .csv, .sav or .txt file. Then use its web link.



If the codes do not support interactive RWeb, just use [code lang="r"] ... [/code]. The following is a demo

library(sem);
example(cfa);

Usually, interactive practices will be presented as videos. Most video platforms provide automatic embedding flash sharing codes like --

<object width="640" height="360">
<param name="movie" value="http://swf.ws.126.net/openplayer/v02/-0-2_M8H1NPQM9_M8H1USJL6-vimg1_ws_126_net//image/snapshot_movie/2012/12/N/2/M8HHDCCN2-.swf"></param>
<param name="allowScriptAccess" value="always"></param><param name="wmode" value="transparent"></param>
  <embed src="http://swf.ws.126.net/openplayer/v02/-0-2_M8H1NPQM9_M8H1USJL6-vimg1_ws_126_net//image/snapshot_movie/2012/12/N/2/M8HHDCCN2-.swf" type="application/x-shockwave-flash" width="640" height="360" allowFullScreen="true" wmode="transparent" allowScriptAccess="always"></embed>
</object>

See the embedded video if your browser supports flash --
