Thanks for the help; I downloaded the April 1 package and the docstrings are
much better. Still having some problems, though. Triangular is
straightforward:
>>>from scipy import stats
>>>triangRV = stats.triang(.7, loc=0, scale=2)
>>>triangRV.rvs(10)
array([ 0.6086996 , 1.30631752, 0.60636975, 0.8502878 , 1.2694698 ,
0.79918653,
1.51063519, 1.12854753, 1.35386416, 0.63519953])
>>>
But truncated normal is not:
>>>truncnormRV = stats.truncnorm(0, 0.7, loc=0, scale=2)
>>>truncnormRV.rvs(10)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "C:\Python23\Lib\site-packages\scipy\stats\distributions.py", line
125, in rvs
return self.dist.rvs(*self.args,**kwds)
File "C:\Python23\Lib\site-packages\scipy\stats\distributions.py", line
440, in rvs
vals = reshape(self._rvs(*args),size)
TypeError: _rvs() takes exactly 1 argument (3 given)
>>>
Any idea where I'm going wrong?
