Examples of EstimatedParameter

org.apache.commons.math.estimation.EstimatedParameter
This class represents the estimated parameters of an estimation problem.
The parameters of an estimation problem have a name, a value and a bound flag. The value of bound parameters is considered trusted and the solvers should not adjust them. On the other hand, the solvers should adjust the value of unbounds parameters until they satisfy convergence criterions specific to each solver.
