    Area of Science:

    • Time Series Analysis
    • Statistical Modeling
    • Signal Processing

    Background:

    • Linear filter models are fundamental in time series analysis.
    • These models can be classified as autoregressive (AR), moving average (MA), or mixed autoregressive-moving average (ARMA).
    • Distinguishing between these model types and their orders is crucial for accurate analysis.

    Purpose of the Study:

    • To develop a practical procedure for discriminating between linear filter model types.
    • To determine the order (k) of short time series data.
    • To aid in the accurate classification of time series models.

    Main Methods:

    • The study focuses on differentiating linear filter models.
    • A working procedure is detailed for the discrimination process.
    • The method is specifically designed for short time series.

    Main Results:

    • A clear procedure for classifying time series into AR, MA, or ARMA models is provided.
    • The method enables the determination of the model order 'k'.
    • Effective discrimination of short time series models is demonstrated.

    Conclusions:

    • The proposed working procedure offers a reliable method for time series model discrimination.
    • Accurate identification of model order is achievable even for short series.
    • This contributes to more precise time series analysis and forecasting.
