#864: Documentation for scipy.interpolate FITPACK interface is misleading
(wrong?)
--------------------------------+-------------------------------------------
Reporter: oanjao | Owner: somebody
Type: defect | Status: closed
Priority: normal | Milestone: 0.8.0
Component: scipy.interpolate | Version: devel
Resolution: fixed | Keywords: interpolate spline documentation
--------------------------------+-------------------------------------------
Changes (by rgommers):
* status: new => closed
* resolution: => fixed
Comment:
Docs have improved a lot and seem to contain all Pauli's comments, for
parameter s it now says:
Positive smoothing factor used to choose the number of knots. Number of
knots will be increased until the smoothing condition is satisfied:
{{{
sum((w[i]*(y[i]-s(x[i])))**2,axis=0) <= s
}}}
If None (default), s=len(w) which should be a good value if 1/w[i] is an
estimate of the standard deviation of y[i]. If 0, spline will interpolate
through all data points.
