This group project was done in March, 2021. Our team aimed to predict the monthly average of CO2 level in April, 2021 based on historical data from Mauna Loa Observatory. We used the dataset of monthly mean carbon dioxide (total of 168 months) measured at Mauna Loa Observatory, Hawaii. We utilized ITSM software to fit the ARMA(1,1) model on the residuals and predicted the exact same value as the acctual value.
