Decomposition with the Mixed Model in Time Series Analysis using Buys-Ballot Procedure

Kelechukwu C. N. Dozie & Christian C. Ibebuogu · Asian Journal of Advanced Research and Reports · 2023

This article provides a general overview of the decomposition with the mixed model. The decomposition of such series into various components requires a method that can adequately estimate and investigate the trend parameters, seasonal indices and residual component of the series....
