Problem set 3. (max 20 points) We operate data on food-related expenditure and total expenditure for US households in 1995. The purpose of our study is to explain how the share of food expenditure on total expenditure (variable share_exp_food measured in ratio from 0 to 1) depends on the total expenditure of the household (variable total_exp measured in US$). Below, R code and output are provided for three regression models fitted to this data alonga with the relevant summary statistics. Use it to answer the following sub-questions: Descriptive statistics: food_dta %>% psych:: describe (skew = F, ranges = F) %>% print (agets=4) ** sd *# share_exp_food 0.1449 0.0852 0.0029 ## total_exp 2 868 29949.4083 19443.3978 659.9519 plot (share_exp_food total_exp, food_dta) mean se vars n 1868 06 - DOG) OS po 02 08 00 100000 150000 50000 total ## Model 1 modell 101) ## (Intercept) 2.1144-01 4.583e-03 46.11 101) ** (Intercept) 0.93299 0.03625 25.73 It!) ** (Intercept) 3.16627 0.24430 12.96
