Female is an indicator variable that equals 1 for wwomen and 0 for men. Midwest, South, and West are indicator variables denoting the region of the United States in which the worker lives: For example, Midwest equals 1 if the worker lives in the Midwest and equils 0 otherwise (the omitted region is Northeast). Standard emors are reported in parentheses below the estimated coefficients. Individual coefficients are statistically significant at the "5% or 1% significance level. Scenario A Consider a man with 18 years of education and 4 years of experience who is from a westem state. Use the results from column (4) of the table and the method in Key Concept 8.1 to estimate xpected change in the logarithm of average hourly earnings (AHE) associated with an additional year of experience he expected change in the logarithm of average hourly earnings (AME) associated with an additional year of experience is (Round your response to two decimal places)

We can use the eigenvalues and eigenvectors of ATA to express A = UΣVT as the multi- plication of three matrices U, Σ and V. The matrix Σ = 8) is a "diagonal" matrix consisting of oi's called the singular values. The values o; are formed by the square root of the positive eigenvalues of AT A ordered in decreasing order. 01 0 0 02 = • The matrix V consists of columns vectors ; called right singular vectors of A. The vectors ;'s are eigenvectors of AT A normalised so that ||vi|| 1 with respect to the standard inner product on R³. The ordering of 7; should be the same as that for σ¿. • The matrix U consists of columns vectors u¡ called left singular vectors of A. If defined, the vectors u¡ can be extracted by the identity u¡j Av. (Note: In the next part, we will show that this identity is applicable for a more general m × n matrix). Evaluate the matrices U, Σ, and V for A and validate that A = UΣVT. = σj
