+%description
+Solve first order autocorrelation problems using an iterative method. This
+procedure estimates both autocorrelation and beta coefficients recursively
+until we reach the convergence (8th decimal as default). The residuals are
+computed after estimating Beta using EGLS approach and Rho is estimated
+using the previous residuals.
