Application of Regression Models for Area, Production and Productivity Growth Trends of Cotton Crop in India

摘要

Computing the growth of any entity over a time period is important for understanding the past behaviour and for future planning. 'Compound growth rate' is one of the frequently used methods for calculating the growth rate models. Among the statistical study was carried out on different growth models viz., linear, quadratic, cubic, exponential, compound, logarithmic, inverse, power, growth and S-curve models to project the area, production and productivity cotton crop in India for 1951 to 2013. The study revealed that through all models exhibited significant; the cubic model is the best fitted, for its highest adjusted R~2 on increasing future projection trends with respect to area, production and productivity of cotton in India.
