Method Detail

addback to summary
public void add(double x, double y)

Adds a point to the sample. Calling this method is equivalent to calling add(1.0, x, y).

Parameters
x:double

Abscissa of the point.

y:double

Observed value at x. After fitting we should have f(x) as close as possible to this value.

public void add(double weight, double x, double y)

Adds a point to the sample.

Parameters
weight:double

Weight of the observed point.

x:double

Abscissa of the point.

y:double

Observed value at x. After fitting we should have f(x) as close as possible to this value.

public void add(WeightedObservedPoint observed)

Adds a point to the sample.

Parameters
observed:WeightedObservedPoint

Observed point to add.

public void clear()

Removes all observations from this container.

toListback to summary
public List<WeightedObservedPoint> toList()

Gets a snapshot of the observed points. The list of stored points is copied in order to ensure that modification of the returned instance does not affect this container. Conversely, further modification of this container (through the add or clear methods) will not affect the returned list.

Returns:List<WeightedObservedPoint>

the observed points, in the order they were added to this container.
