| Summary: | The monsoon is affected by factors like wind speed, humidity, and temperature. Outliers can signiicantly skew the data, and this study presents an outlier detection method using the COVRATIO statistic, derived from the covariance matrix within a simultaneous Linear Functional Relationship Model (LFRM) for linear variables. The cut-off point for the 5% upper percentiles of the maximum value of the COVRATIO statistic is established through a Monte Carlo simulation study. The indings indicate that outliers are detected when the COVRATIO statistic surpasses these cut-off points. The effectiveness of the simultaneous LFRM is demonstrated using Butterworth environmental data, with variables including wind speed, humidity, and temperature. The data's normality is conirmed by the Kolmogorov-Smirnov test. This research supports the National Policy on Climate Change by contributing to knowledge-based decision-making in climate-related studies, particularly in the domains of environmental monitoring, renewable energy planning, and data analysis. © 2024 Institute of Physics Publishing.
