(Sudan University of Science & Technology, 2021-12-19)Constructing an econometric model to be suitable for forecasting necessarily requires that it should be free from measurement problems (Heterocedasticity, Auto-correlation and Multicollinearity). The main object of this ...
-
(Sudan University of Science & Technology, 2022-02-08)Seeds are widely used for human food and food supplements. Water is mainly used as its host environment. This requires studying their properties separately and this work stems from the importance of seeds in human life. ...
