title: What estimators does seaborn support
body: <p>Seaborn allows the user to input &quot;estimator&quot; variable in its various plots, for example:
  <a href="https://seaborn.pydata.org/generated/seaborn.catplot.html" rel="nofollow noreferrer">https://seaborn.pydata.org/generated/seaborn.catplot.html</a></p>
  <p>I understand that the estimator should be a function of &quot;vector&quot; to &quot;scalar&quot; i.e. &quot;mean&quot; takes vector to and outputs a scalar (it's average value).</p>
  <p>So far, I found &quot;mean&quot; and &quot;sum&quot; to be valid estimators, while &quot;median&quot; is not. Are there any other?</p>
