Please, use GAMS for the nonlinear regression form that provides an optimal fit

Problem 1 (20 pts) Suppose cost data for the NLP example discussed in class (see slides for NLP) are summarized in Table 1 below. Please calculate the values of xy and X2 using GAMS for the nonlinear regression form f(n) = xin*2 that provides an optimal fit. Table 1. Cost Data for the NLP Example.
