Modelling Tap Water Consumer Ratio

Blog Article

Increasing population and the rising air temperatures are known as factors that cause water depletion in the watersheds.Therefore, it is important to accurately predict the future ratios of tap water consumers using the same watershed to the population living in the specified area, hobbit door for sale to produce better water policies and to take the necessary measures.Predictions can be made by a growth curve model (GCM).Parameter estimations of the GCM are usually based on the ordinary least square (OLS) estimator.

However, the outlier presence affects the estimations and the predictions, which are obtained by using the estimated model.The present article attempts to construct first- and third-order GCMs with robust least median square (LMS) and M estimators to make short-term predictions of ratios of tap water consumers.According to the findings, parameter estimations of the models, the outliers, and the predictions vary with respect to sex shop arles the estimators.The M estimator for short-term predictions is suggested for use, due to its robustness against outlier points.
