title: Calculate mean and standard deviation from a vector of samples in C++ using Boost
body: <p>Is there a way to calculate mean and standard deviation for a vector containing samples using <a href="http://en.wikipedia.org/wiki/Boost_%28C%2B%2B_libraries%29" rel="noreferrer">Boost</a>? </p>
  
  <p>Or do I have to create an accumulator and feed the vector into it?</p>
