Cross-Price and Income Elasticity of Demand
Q: What does income elasticity of demand measure?
Did You Know?
Standard error of b₂ is sqrt(s²_u / Σ(X_i - X̄)²). It increases when (1) s²_u (estimated error variance) is larger, or (2) Σ(X_i - X̄)² (total variation in X) is smaller. Less variation in X reduces precision and increases standard error.
