(14 marks) Fortune magazine publishes a list of the worldā€™s billionaires each year. We will examine the top 97 of the 1992 list. Their wealth, age, and geographic location (Asia, Europe, Middle East, United States, and Other) are reported. Wealth is a right-skewed variable, so we will consider the natural logarithm log wealth to be the response and will see if age and geographic location are predictors.
(a) (2 marks) Let
Ebe a variable that is 1 if the person is from Europe and 0 otherwise,
Mbe a variable that is 1 if the person is from the Middle East and 0 otherwise,
Obe a variable that is 1 if the person is from the ā€œOtherā€ region and 0 otherwise,
and
Ube a variable that is 1 if the person is from the United States and 0 otherwise.
State a linear model for the mean of log wealth that includes age and the above 4
geographic variables. Call this the full model.
(b) (5 marks) The SSY for these data is 28.3351 and the SSE from ļ¬tting the full model
is 27.0461. Use this information to construct an ANOVA table. Your table should
include columns for Source, df, SS, MS and F, and should include rows for the model
(full model), residual and total.
(c) (2 marks) In addition to the full model, the reduced model that includes only an
intercept and age is ļ¬t. What is the null hypothesis being considered by ļ¬tting these
two models? (Refer to quantities deļ¬ned in your model.)
(d) (3 marks) The SSM from the reduced model is 59.7. Calculate an F-statistic to test the hypothesis of part (c). State the degrees of freedom for the F-distribution
you would compare this statistic to. (You do not need to calculate the p-value or actually test the hypothesis.)
(e) (1 mark) Using terminology from class, name the kind of Ftest that the statistic in part (d) corresponds to.
(f) (1 mark) If the null model for these data is compared to the model that includes an
intercept and age, what are the results?
