convert_set_to_family_of_curves

arithmeticmeancurve.convert_set_to_family_of_curves(set_of_curves: List[pandas.core.frame.DataFrame]) → pandas.core.frame.DataFrame

Merges and interpolates a set into a family (of curves).

Notes

The family of curves is the basis for a mean curve calculation.

Parameters

set_of_curves (SetOfCurves) – A set of unique curves, which doesn’t share common x-values.

Returns

DataFrame
