Hi, <br>I just updated scipy from svn and stats.linregress(x,y) returns <br><br>/usr/lib/python2.4/site-packages/stats.py in __call__(self, arg1, *args, **kw)<br>&nbsp;&nbsp;&nbsp; 244&nbsp;&nbsp;&nbsp;&nbsp; def __call__(self, arg1, *args, **kw):<br>&nbsp;&nbsp;&nbsp; 245&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if type(arg1) not in self._types:
<br>--&gt; 246&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; raise TypeError, &quot;don't know how to dispatch %s arguments&quot; %&nbsp; type(arg1)<br>&nbsp;&nbsp;&nbsp; 247&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return apply(self._dispatch[type(arg1)], (arg1,) + args, kw)<br>&nbsp;&nbsp;&nbsp; 248<br><br>TypeError: don't know how to dispatch &lt;type '
numpy.ndarray'&gt; arguments<br><br>Also, in ipython, linregress? returns a doc about the dispatch class. Is this intended ? <br><br>David<br>
