A simple procedure to include the R-squared and Root Mean Square Error (R.M.S.E) is proposed and tested. The results showed that the Partial Least Square Regression provides better predictions due to a small R.M.S.E value. 200%">Keyword.

Secondary data collected from Coca- Cola Company, Idokpa,Benin City Plant was analysed using Control Chart for process variability andprocess average. Through the application of statistical Quality Controltechnique, the product quality was examined and process contr...
ABSTRACTIn this project, Partial Least Square Regression was compared with Ordinary Least Square Regression (OLSR) to handle the problem of multicollinarity and small sample size on all Nigeria Insurance Company’s expenditure data. The prediction methods have been compared for efficiency through Root Mean Square Error (RMSE) and Mean Square Error (MSE). It is found that in this project Partial Least Square Regression (PLSR) provides better prediction as compared to the Ordinary Least S...

ABSTRACTThis research work was aimed at carrying out statistical analysis of federal government’s revenue and expenditure 2003-2008. Secondary data was obtained from National Bureau of Statistics. The statistical package used is Mintab. The result of the analysis shows that there is positive and strong relationship between expenditure and revenue 0.938 and the regression equation is expenditure = 123 + 0.367 revenue. The regression equation shows that when the revenue increase, the expendit...
