    Abstract: In most research fields, the amount of data produced is growing very fast. Analysis of big data offers potentially unlimited opportunities for information discovery. However, due to the high dimensions and presence of outliers, there is a need for a suitable algorithm for dimensionality reduction. By performing dimensionality reduction, we can lear... Show More

    Abstract: This project analyzes the monthly average rainfall and temperature from 2005 January to 2021 December in Minot, ND, USA. Since both rainfall and temperature time series represent seasonal components, Seasonal Auto Regressive Integrated Moving Average (SARIMA) models were used to forecast the average rainfall and temperature. The main objective was ... Show More
