Uses cubic spline fitting to smooth an input data set.
Dependent values. y must contain at least two points.
Independent values. x must be the same size as y. The elements of x must be in ascending order.
Weights for the observations.
weight must be the same size as y. weight also must contain non-zero elements. If an element in weight is less than 0, this node uses the absolute value of the element. If you do not wire an input to weight, this node sets all elements of weight to 1.
Smoothness for each interval between two contiguous data points.
The larger the smoothness, the smoother the curve. The number of elements in smoothness n - 1, where n is the length of y. If smoothness is unwired, this node sets all elements of smoothness to 1.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
Balance between the smoothness of the cubic spline fit and the accuracy with which it fits the observations.
balance parameter must fall within the range [0, 1]. If balance parameter is 0, the cubic spline fit is equivalent to a linear fit. If balance parameter is 1, the cubic spline fit interpolates between the data points. If balance parameter is out of the range [0, 1], this node calculates an appropriate value for balance parameter automatically according to the values of x.
Y-values of the fitted model.
Error information. The node produces this output according to standard error behavior.
This node fits the observations (x, y) by minimizing the following function:
