<P>
This class represents measurements in estimation problems.

 <p>This abstract class implements all the methods needed to handle
 measurements in a general way. It defines neither the <A HREF="../../../../../org/apache/commons/math/estimation/WeightedMeasurement.html#getTheoreticalValue()"><CODE>getTheoreticalValue</CODE></A> nor the <A HREF="../../../../../org/apache/commons/math/estimation/WeightedMeasurement.html#getPartial(org.apache.commons.math.estimation.EstimatedParameter)"><CODE>getPartial</CODE></A> methods, which should be defined by
 sub-classes according to the specific problem.</p>

 <p>The <A HREF="../../../../../org/apache/commons/math/estimation/WeightedMeasurement.html#getTheoreticalValue()"><CODE>getTheoreticalValue</CODE></A> and <A HREF="../../../../../org/apache/commons/math/estimation/WeightedMeasurement.html#getPartial(org.apache.commons.math.estimation.EstimatedParameter)"><CODE>getPartial</CODE></A> methods must always use the current
 estimate of the parameters set by the solver in the problem. These
 parameters can be retrieved through the <A HREF="../../../../../org/apache/commons/math/estimation/EstimationProblem.html#getAllParameters()"><CODE>EstimationProblem.getAllParameters</CODE></A> method if the measurements are
 independent of the problem, or directly if they are implemented as
 inner classes of the problem.</p>

 <p>The instances for which the <code>ignored</code> flag is set
 through the <A HREF="../../../../../org/apache/commons/math/estimation/WeightedMeasurement.html#setIgnored(boolean)"><CODE>setIgnored</CODE></A> method are ignored by the
 solvers. This can be used to reject wrong measurements at some
 steps of the estimation.</p>
