In many forms of regression for categorical variables a reference level must be declared. Coefficients for other levels of a categorical variable are then interpreted in relation to the reference level. For instance, consider predicting income (a continuous variable) from race (1 = White, 2 = African-American, 3 = Other), where the "1" category is the reference level for race, then a coefficient of -0.7 for African-American would mean that compared to the reference level (White), African-Americans are predicted to have lower income.
