Hi, I would like to know if its possible in matlab to get the equation of the lowess or spline filter's equation. This equation i would like to further apply to predict my test data.

Hi,
The Curve Fitting toolbox has several nonparametric fitting options, including:
  • Interpolation Methods
  • Smoothing Splines
  • Lowess Smoothing
Here is an article about Lowess Smoothing in MATLAB.
