title: using scipy's stats.linregress with a fixed y intercept
body: <p>I was wondering if it was possible to use stats.linregress except with a fixed y-intercept, I am currently doing this,:</p>
  
  <pre><code>from scipy import stats
  from numpy import arrange,array
  
  y = [0, 11, 19, 28, 41, 49, 62, 75, 81]
  xi = arange(0,9)
  
  scale, intercept, r_value, p_value, std_err = stats.linregress(xi,y)
  </code></pre>
  
  <p>It would be preferrable if I could still ascertian a R value</p>
