Interpolation methods

Interpolation methods in TATSSI

xarray

TATSSI stores the time series objext in a Python xarray, xarrays allows differnt interpolation methods using the interpolate_na class method.

• When the interpolation is linear xarray uses the numpy interpolation linear method

• For all other interpolation methods xarray uses SciPy

• For nearest, zero, slinear, quadratic, cubic xarray uses the inter1d class method.

• For krog, pchip, spline, and akima xarray uses the corresponding scipy.interpolate class method:

  • krog
  • pchip
  • spline
  • akima

• For quadratic or cubic xarray will use the interp1d class method as well.
