title: t-values and Pr(>|t|) for coefficients of numpy.polyfit
body: <p>I want to determine the significance of the coefficients in a polynomial model fitted to some data using numpy.polyfit. </p>
  
  <p><a href="http://www.r-bloggers.com/polynomial-regression-techniques/" rel="nofollow">This</a> is an example of what I want to achieve using R. Basically, I need to get what R's "summary" function outputs with scipy/numpy. Is there an easy way to do this with scipy/numpy (some built-in helper function?) or should I just go with <a href="http://rpy.sourceforge.net/" rel="nofollow">rpy</a> instead?</p>
