Evaluation of models with time-varying parameters is widely used in macroeconomic

various authors have begun to apply such models to analyze the time-varying behavior of such
macroeconomic parameters such as volatility, long-term economic growth, trend inflation,
persistence of inflation and oil prices, as well as the dependence of the main macroeconomic variables on oil prices
