title: Seeking a statistical javascript function to return p-value from a z-score
body: <p>I need to convert z-scores to percentile. I found reference to a <a href="http://jstat.github.io/test.html#jStat.ztest" rel="noreferrer">function in the jStat library</a> that I could use (jstat.ztest), but the jStat documentation seems to be ahead of the available library because there is no such function in the <a href="http://www.jstat.org/jstat-1.0.0.js" rel="noreferrer">currently available version of the library</a>. </p>
  
  <p>I think there is a <a href="https://github.com/jstat/jstat" rel="noreferrer">more recent version of the library on GitHub</a>, which may include the ztest function, but I am a linux novice and could not figure out how to build the library from the instructions. I spent most of a day learning about git bash and cygwin trying to build the library; I finally decided I'd be better off asking here.</p>
  
  <p>So, could anyone point me toward a javascript function that would do what I need?
  Alternatively, could anyone point me toward a built version of the jStat library with ztest function included?</p>
