title: Scipy eqilivent of the matlab function pkurtosis
body: <p>I'm trying to convert into python (numpy/scipy) the following matlab code:</p>
  <pre><code>[spectrum, frequency] = pkurtosis (signal, sample_rate);
  </code></pre>
  <p>The matlab <a href="https://www.mathworks.com/help/signal/ref/pkurtosis.html" rel="nofollow noreferrer">pkurtosis help</a> page calls the algorithm spectral kurtosis. I'm looking for a scipy function that will give me the equivalent results. Does such a function exist or am I going to have to code it up manually in python?</p>
