Is Fourier Series Analysis Better Than Multiple Linear Regression Analysis In Modeling Inflation In The Food Sector?

In conclusion, I agree with the results of the research in the above article regarding the inflation modeling of the food sector in Indonesia using the Fourier series analysis, which states that the Fourier series analysis has better modeling results than multiple linear regression analysis. The use of data in the form of monthly data makes the results of modeling the two analyzes different. Where there will be data patterns that affect the results of the analysis. By using Fourier series analysis can produce better modeling because it can overcome the problem of data patterns contained in the study. Whereas in multiple regression analysis only looks at the relationship between variables without paying attention to the presence of data patterns.(rls)
