       abstract = "A software technique is described that provides support for uncertainty
         calculations for complex-valued measurements. The technique is based on classical methods of
         multivariate statistics and propagation of variance as well as automatic differentiation, which is
         an established computational method. It facilitates propagation of covariance data by automating the
         calculation of sensitivity coefficients. The technique introduces a simple abstraction to represent
         measurement data and defines arithmetic operations and standard functions that manipulate this
         abstraction. The method is not difficult to implement and is easy to use. An example source code in
         C++ is included.",
