[SciPy-user] stats.anova problem

[Louis Luangkesorn]

Hello

I'm trying to test the anova package.  But I'm doing something
wrong here.  This is what I try.

import scipy
anovadata = ([[1,'A1','B1',2],
              [2,'A1','B1',1],
              [3,'A1','B1',3],
              [4,'A1','B1',2],
              [5,'A1','B2',3],
              [6,'A1','B2',4],
              [7,'A1','B2',5],
              [8,'A2','B1',4],
              [9,'A2','B1',6],
              [10,'A2','B1',5],
              [11,'A1','B2',2],
              [12,'A1','B2',4],
              [13,'A1','B2',5]])

y=scipy.stats.anova(anovadata)


Then, I get:

Traceback (most recent call last):
  File "C:\apps\Python\Pythonwin\pywin\framework\scriptutils.py",
line 301, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Documents and Settings\kll560\My
Documents\testdata\anovatest.py", line 16, in ?
    y=scipy.stats.anova(anovadata)
  File "C:\apps\Python\scipy\stats\stats.py", line 234, in __call__
    return apply(self._dispatch[type(arg1)], (arg1,) + args, kw)
  File "C:\apps\Python\scipy\stats\stats.py", line 3933, in aanova
    M = pstat.collapse(data,Bscols,-1,None,None,mean)
TypeError: collapse() takes at most 5 arguments (6 given)


By the way, in pstats.py, the call for collapse() is in line 183:

def collapse
(listoflists,keepcols,collapsecols,sterr=None,ns=None):

Any ideas?
