ECON241: Multiple Regression and Inference Assignment

This assignment solution addresses a series of econometrics problems related to multiple regression and inference. The solution begins with interpreting OLS output, including coefficients and R-squared values, and moves on to hypothesis testing using t-ratios, p-values, and confidence intervals. It explores ANOVA tables, critical value approaches, and the implications of rejecting or accepting null hypotheses. The solution also covers testing the sum of coefficients, collinearity, and the relationship between variables. Each question includes detailed interpretations of the results, along with the relevant Gretl outputs and statistical analyses. The assignment provides a comprehensive understanding of econometric methods and their application in analyzing economic models.
