rawdata = ReadList["energy.dat", Real];
data = Partition[rawdata, 10];
ListPlot3D[data, AspectRatio -> 1, Mesh -> False,
ColorFunction -> (ColorData["ThermometerColors"])]
then the output is:
ListPlot3D::arrayerr: data must be a valid array or a list of valid arrays.

" analyze those 5 variables all together"
请google: multivariate ANOVA..
简单的说,你这5个response variale如果是independent的,那很好办啦,就一个一个的
做ANOVA就行了(不过你要adjust significant level)..
而MANOVA就是把这5个response当作一个vector,然后去比较你这A,B,C,D的response
vector有没有significant different..而test用的方法基本都是非参的方法..
SAS里面实现MANOVA的例子:
PROC GLM DATA=RAWDATA;
CLASS GROUP;
MODEL Y1 Y2 Y3 Y4 Y5 = GROUP;
manova h=_all_ / printe printh;
然后你的output会有,Wilks' Lambda,Pillai's Trace,Hotelling-Lawley Trace等方法
的test结果..你自己选一个用就行了.
至于要不要用 |

When attempting to minimize memory usage, the most efficient way to do group
processing whenusing the MEANS procedure is to use:
A. the BY statement.
B. GROUPBY with the NOTSORTED specification.
C.the CLASS statement.
D.multiple WHERE statements.
答案选C，个人也认为C是对的。网上有人提到过用Sort再means,这样A更快。但是题目
问的是memeory，不是时间，所以觉得还是应该选C。
