Robust Standard Errors (Regression)

Using the maize only version of eth_allrounds_final.dta with per hectare inputs, compare default and robust standard errors.

• Run reg yield_kg fert labor i.irr i.admin_1 (default standard errors).
• Run the same regression with , robust appended.

1. Did the coefficients change?
2. How did the standard error on fert change?
3. Did the p-value on fert change in a way that would affect your conclusions?
