The Monthly Nigeria External Reserves is usually lower during the fifth, sixth, tenth, eleventh and twelfth months of each year with a drop of about US$27.19, US$42.48, US$21.09, US$73.88 and US$72.75 below average. The plot of the periodic mean and the periodic standard deviation showed that the additive model fitted the research data. Between the first month of 2015 and the twelfth of 2015, the Monthly Nigeria External Reserves would range between US$32.46 and US$23.82.
