		Option_t *	option = `"linear"`,
		Int_t	nout = `50`,

		Double_t	yright = `0`,

		Double_t	f = `0`,
		Option_t *	ties = `"mean"`
	)

Approximate data points.

Parameters

[in]	grin	graph giving the coordinates of the points to be interpolated. Alternatively a single plotting structure can be specified:
[in]	option	specifies the interpolation method to be used. Choices are "linear" (iKind = 1) or "constant" (iKind = 2).
[in]	nout	If xout is not specified, interpolation takes place at n equally spaced points spanning the interval [min(x), max(x)], where nout = max(nout, number of input data).
[in]	xout	an optional set of values specifying where interpolation is to take place.
[in]	yleft	the value to be returned when input x values less than min(x). The default is defined by the value of rule given below.
[in]	yright	the value to be returned when input x values greater than max(x). The default is defined by the value of rule given below.
[in]	rule	an integer describing how interpolation is to take place outside the interval [min(x), max(x)]. If rule is 0 then the given yleft and yright values are returned, if it is 1 then 0 is returned for such points and if it is 2, the value at the closest data extreme is used.
[in]	f	For method="constant" a number between 0 and 1 inclusive, indicating a compromise between left- and right-continuous step functions. If y0 and y1 are the values to the left and right of the point then the value is y0f+y1(1-f) so that f=0 is right-continuous and f=1 is left-continuous
[in]	ties	Handling of tied x values. An integer describing a function with a single vector argument returning a single number result: ties = "ordered" (iTies = 0): input x are "ordered" ties = "mean" (iTies = 1): function "mean" ties = "min" (iTies = 2): function "min" ties = "max" (iTies = 3): function "max"

Details:

At least two complete (x, y) pairs are required. If there are duplicated (tied) x values and ties is a function it is applied to the y values for each distinct x value. Useful functions in this context include mean, min, and max. If ties="ordered" the x values are assumed to be already ordered. The first y value will be used for interpolation to the left and the last one for interpolation to the right.

Value:

approx returns a graph with components x and y, containing n coordinates which interpolate the given data points according to the method (and rule) desired.

Parameters

[in]	n	number of observations (x,y - pairs).
[in]	x	ordered abscissa values.
[in]	y	corresponding ordinate (response) values.
[in]	w	weight for each (x,y) observation.
[in]	iper	periodic variable flag. iper=1 => x is ordered interval variable. iper=2 => x is a periodic variable with values in the range (0.0,1.0) and period 1.0.
[in]	span	smoother span (fraction of observations in window). span=0.0 => automatic (variable) span selection.
[in]	alpha	controls high frequency (small span) penality used with automatic span selection (bass tone control). (alpha.le.0.0 or alpha.gt.10.0 => no effect.)
[out]	smo	smoothed ordinate (response) values.
	sc	internal working storage.

note:

for small samples (n < 40) or if there are substantial serial correlations between observations close in x - value, then a prespecified fixed span smoother (span > 0) should be used. reasonable span values are 0.2 to 0.4.

Smooth data with Kernel smoother.

Smooth grin with the Nadaraya-Watson kernel regression estimate.

Parameters

[in]	grin	input graph
[in]	option	the kernel to be used: "box", "normal"
[in]	bandwidth	the bandwidth. The kernels are scaled so that their quartiles (viewed as probability densities) are at +/- 0.25*bandwidth.
[in]	nout	If xout is not specified, interpolation takes place at equally spaced points spanning the interval [min(x), max(x)], where nout = max(nout, number of input data).

		Double_t	delta = `0`
	)

Smooth data with Lowess smoother.

This function performs the computations for the LOWESS smoother (see the reference below). Lowess returns the output points x and y which give the coordinates of the smooth.

Parameters

[in]	grin	Input graph
[in]	span	the smoother span. This gives the proportion of points in the plot which influence the smooth at each value. Larger values give more smoothness.
[in]	iter	the number of robustifying iterations which should be performed. Using smaller values of iter will make lowess run faster.
[in]	delta	values of x which lie within delta of each other replaced by a single value in the output from lowess. For delta = 0, delta will be calculated.

		Double_t *	w = `0`
	)

Smooth data with Super smoother.

Smooth the (x, y) values by Friedman's ``super smoother''.

Parameters

[in]	grin	graph for smoothing
[in]	span	the fraction of the observations in the span of the running lines smoother, or 0 to choose this by leave-one-out cross-validation.
[in]	bass	controls the smoothness of the fitted curve. Values of up to 10 indicate increasing smoothness.
[in]	isPeriodic	if TRUE, the x values are assumed to be in [0, 1] and of period 1.
[in]	w	case weights

Details:

supsmu is a running lines smoother which chooses between three spans for the lines. The running lines smoothers are symmetric, with k/2 data points each side of the predicted point, and values of k as 0.5 * n, 0.2 * n and 0.05 * n, where n is the number of data points. If span is specified, a single smoother with span span * n is used.

The best of the three smoothers is chosen by cross-validation for each prediction. The best spans are then smoothed by a running lines smoother and the final prediction chosen by linear interpolation.

The FORTRAN code says: ``For small samples (n < 40) or if there are substantial serial correlations between observations close in x - value, then a prespecified fixed span smoother (span > 0) should be used. Reasonable span values are 0.2 to 0.4.''
