%! ## Compute the standard deviation for a Piecewise Linear distribution
%! load patients
%! [f, x] = ecdf (Weight);
%! pd = PiecewiseLinearDistribution (x(1:5:end), f(1:5:end));
%! std_value = std (pd)
%!
%! ## Use this to calculate the standard deviation, measuring variability
%! ## in the empirical distribution.
