Method Detail

setModel

public void setModel(M model)

Description copied from interface: ResidualCalculator

Set the current model being evaluated. This should be called every time the model has changed internally, as the ResidualCalculator might pre-cache variables based on the model for error computation.

Specified by:

setModel in interface ResidualCalculator<I,D,M extends Model<I,D>>

Parameters:

model - the model

computeResiduals

public void computeResiduals(List<? extends IndependentPair<I,D>> data,
                             double[] errors)

Description copied from interface: ResidualCalculator

Compute the residual for a set of data points

Specified by:

computeResiduals in interface ResidualCalculator<I,D,M extends Model<I,D>>

Parameters:

data - the data

errors - the array to write the residuals into
