The Spillover Effect of Agricultural Product Market Price Fluctuation Based on Fourier Analysis

The stability of the original spillover effect model agricultural product market price volatility is poor, resulting in low degree fitting between results and actual situation. In order to further clarify volatility, a research method based on Fourier analysis proposed. authors collect sample data, eliminate missing complete data storage. Wavelet transform used reduce noise reconstruct with high discretization aggregated output preprocessing results. experimental show that has strong anti-interference ability, good stability, actual, reliability.
