title: weak instruments stata results
body: <p>I'm using the command ivregress 2sls, with clusters (each cluster is a school) and with pweights.</p>
  <p>I have one endogenous variables x1, and 4 instruments. I'm trying to test my model and check if my instruments are not weak.</p>
  <p>I used the estat firstatage command and I'm not sure how to interpret the result.
