    This study introduces a new numerical method for analyzing unknown functional connections in measured data. The approach offers a model-free way to represent data trends, providing a continuous curve with a continuous first derivative for better analysis.

    Area of Science:

    • Numerical analysis
    • Data science
    • Applied mathematics

    Context:

    • Analyzing complex time series data with unknown functional relationships.
    • Limitations of existing methods like nonlinear and segmented linear regression.
    • Need for robust methods for data smoothing and interpolation.

    Purpose:

    • To present a novel, model-free numerical method for representing the mean course of measured data.
    • To demonstrate the method's utility across diverse time series data.
    • To highlight advantages over traditional regression techniques.

    Summary:

    • A new numerical method utilizes a Gaussian-like weight function for local linear regression to create a continuous approximation curve.
    • This curve accurately represents the mean trend in measured data, offering a continuous first derivative.
