"The estimation model for a demand function of daily cigarette consumption is given as follows:

cigs = β0 + β1log(income) + β2log(cigpric) + β3educ + β4age + β5age^2 + β6 restaurn + u

where cigs is the number of cigarettes smpoked per day, income is the annual income, cigpric is the per pack price of cigarettes (in cents), educ is years of schooling, age is measured in years, and restaurn is a binary indicator equal to one if the person resides in a state with restaurant smoking restrictions."


This will be interesting.

I wonder if all this data is real; the dataset also includes the variable "white - =1 if white" - maybe we didn't have that since in Singapore racial discrimination is forbidden.
