Final – take home
Find the assigned data (assignment is listed below) under final exam topic on coursesite. Perform thorough regression analysis (follow the flow as discussed in lecture) and report the result of final model. The tasks expected ranges from exploratory data analysis (descriptive statistics, histogram, scatter plot, … etc.), model-diagnostics/residual-analysis, model selection, evaluation of multi-collinearity, influential points analysis (YES, treat this as million-dollar project), with optional variable transformation, weighted least square or remedy for multi-collinearity. Extra credit is for extra work (either more advanced analytical work or expand the study to compare with data from difference resources).
