Dummy Variable Negative Coefficient

Linear Regression Using Stata - Home | Princeton University
We use regression to estimate the unknown effectof changing one variable over another (Stock and Watson, Two-tail p-values test the hypothesis that each coefficient is different from 0. To reject this, the p- value has to be lower than 0.05 using dummy variables/selecting the reference ... Get Document
