If the ``ties`` parameter is explicitly set to 'ordered' then order is already assumed. Otherwise, the removal process will happen.

Return a list of points which (linearly) interpolate given data points, or a function performing the linear (or constant) interpolation. Parameters ---------- x : array-like, shape=(n_samples,) Numeric vector giving the coordinates of the points to be interpolated. y : array-like, shape=(n_samples,) Numeric vector giving the coordinates of the points to be interpolated. xout : int, float or iterable A scalar or iterable of numeric values specifying where interpolation is to take place. method : str, optional (default='linear') Specifies the interpolation method to be used. Choices are "linear" or "constant". rule : int, optional (default=1) An integer describing how interpolation is to take place outside the interval ``[min(x), max(x)]``. If ``rule`` is 1 then np.nans are returned for such points and if it is 2, the value at the closest data extreme is used. f : int, optional (default=0) 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 y0 if f == 0, y1 if f == 1, and y0*(1-f)+y1*f for intermediate values. In this way the result is right-continuous for f == 0 and left-continuous for f == 1, even for non-finite ``y`` values. yleft : float, optional (default=None) The value to be returned when input ``x`` values are less than ``min(x)``. The default is defined by the value of rule given below. yright : float, optional (default=None) The value to be returned when input ``x`` values are greater than ``max(x)``. The default is defined by the value of rule given below. ties : str, optional (default='mean') Handling of tied ``x`` values. Choices are "mean" or "ordered". zmethod must be one of %rrr r z0need at least two points to linearly interpolate) VALID_APPROXr!rastyper"float64rr/r nanrasarray) rrxoutmethodruleryleftyrightr) method_keyr+youts rr r bsf\!3lBCC T7>>"** %DJ*l 3F q!T "DAq B Qw  !45 5 } !rvv ~!)2 Aq$5& 9D D! !!r)r r rNNr)numpyr" utils.arrayrrutilsr compat.numpyrpmdarima.arima._arimar__all__r2averager%r'r/r rrrrEsb( +     JJ  8v<@#R"r
