HELP WITH STATA COMMANDS (PLEASE JUST RESPOND WITH STATA COMMAND TO USE)

Data Info

Refer to the data fixed_effects_dataset.xlsx:

Dependent variable: fatarate, which is traffic fatality rate (deaths per 10,000).

Independent variable: beertax, which is the measure of alcohol taxes real tax on a case of beer.

Lets only consider a regression model with a single regressor beertax.

Questions

1. use only two years data, 1982 and 1988, generate a entity-fixed effects estimator of the marginal effect of beer tax on the fatality rate?

2. use all the data in the dataset (7 years, from 1982 to 1988), generate entity-fixed effect estimate of the marginal effect of beer tax on the fatality rate.

3. use all the data in the dataset (7 years, from 1982 to 1988), generate time-fixed effect estimate of the marginal effect of beer tax on the fatality rate.

4. use all the data in the dataset (7 years, from 1982 to 1988), generate both entity and time-fixed effect estimate of the marginal effect of beer tax on the fatality rate.
