Regression: Short run production analysis {10 marks] [1} Please estimate a linear production function using the data provided [excel file named \"wheat yield\") for wheat yield [kg/ha) and Nitrogen {N} usage (kg/ha]. You need to visualise the linear production function with the production equation and model fitness shown on the graph. (4 marks) [2} Now reestimate the production function in a quadratic form using the same data provided. As it is in [1}, you need to visualise the quadratic production function with the quadratic equation and model fitness on the graph. (4 marks) [3} Which model suits the data best? Simply explain w_hy. (2 marks)
