Subclasses of LeastSquareResults in com.opengamma.strata.math.impl.statistics.leastsquare

Modifier and Type	Class	Description
class	GeneralizedLeastSquareResults<T>	Generalized least square calculator.
class	LeastSquareResultsWithTransform	Container for the results of a least square (minimum chi-square) fit, where some model (with a set of parameters), is calibrated to a data set, but the model parameters are first transformed to some fitting parameters (usually to impose some constants).
class	LeastSquareWithPenaltyResults	Hold for results of NonLinearLeastSquareWithPenalty.

Methods in com.opengamma.strata.math.impl.statistics.leastsquare that return LeastSquareResults

Modifier and Type	Method	Description
LeastSquareResults	NonLinearLeastSquare.solve(DoubleArray x, DoubleArray y, double sigma, ParameterizedFunction<Double,DoubleArray,Double> func, DoubleArray startPos)	Use this when the model is in the ParameterizedFunction form and analytic parameter sensitivity is not available but a measurement error is.
LeastSquareResults	NonLinearLeastSquare.solve(DoubleArray x, DoubleArray y, double sigma, ParameterizedFunction<Double,DoubleArray,Double> func, ParameterizedFunction<Double,DoubleArray,DoubleArray> grad, DoubleArray startPos)	Use this when the model is in the ParameterizedFunction form and analytic parameter sensitivity and a single measurement error are available.
LeastSquareResults	NonLinearLeastSquare.solve(DoubleArray x, DoubleArray y, DoubleArray sigma, ParameterizedFunction<Double,DoubleArray,Double> func, DoubleArray startPos)	Use this when the model is in the ParameterizedFunction form and analytic parameter sensitivity is not available but an array of measurements errors is.
