6. Consider the linear population model with intercept:$y_t = \alpha + \beta x_t + \varepsilon_t$The variance structure is known as below: $E(\varepsilon_t^2) = \sigma^2 h_t^2,$Which regression may obtain efficiency $\hat{\beta}$ estimator? (A) Regress \( y_{t} \) on 1, \( x_{t} \) (B) Regress \( y_{t} / h_{t} \) on 1/ht ,xt/ht(C) Regress \( y_{t} / h_{t}^{2} \) on 1/h2t ,xt/h2t(D) Regress \( y_{t} \) on 1/ht ,xt/ht(E) Regress \( y_{t} / h_{t} \) on 1, \( x_{t} \)
5. Consider the linear model with intercept: $y_t = \alpha + \beta x_t + u_t$ If the $A = \sum_{i=1}^{n} (x_i - \bar{x})^2$ is positive definite and $E(u_i \mid x_i) = 0, \forall t = 1, 2, \dots, T$, which statement is true under sample size $T \to \infty$. (A) \( \hat{\beta} \) is consistent, but we cannot judge whether \( \hat{\beta} \) is efficiency (B) \( \hat{\beta} \) is unbiased and efficiency (C) \( \hat{\beta} \) is consistent and efficiency (D) \( \hat{\beta} \) is, but we cannot judge whether \( \hat{\beta} \) is efficiency (E) \( \hat{\beta} \) is unbiased and consistent.
4. Consider the simple regression $y_i = \alpha + \beta x_i + \varepsilon_i$And suppose population parameter $\beta = 2$ and least square estimator $\hat{\beta} = 2.3$. Now consider the regression $(x_i - y_i) = \alpha^* + \beta^* x_i + u_i.$What is the value of \( \hat{\beta} \)? (A) 1 (B)-1 (C)-1.3 (D)-0.3 (E) 0.3

複選題59.(AB) In practice, frequent changes in direction under successive presidential administrations have disrupted the continuity necessary for such ambitious undertakings. (AC) Commercial commitments, international commitments and now the government—all three working together is what’s really enabled humans to get to this point. (AD) The United States’ former rivalry with the Soviet Union has transitioned into a more complex competition involving a diverse array of nations with their own strategic lunar objectives. (AE) While Artemis II is a lunar flyby rather than a landing, it marks a significant milestone: the first crewed mission to the lunar vicinity since the Apollo program in 1972. (BC) Much of the industrial infrastructure and specialized expertise that supported the Apollo missions no longer exists, making a direct replication of 1960s technology impractical. (BD) The protracted interval between these landmark missions is fundamentally a byproduct of oscillating political will and shifting national priorities. (BE) This shift requires the development of durable habitats and adaptable landing systems capable of operating in the lunar environment for extended periods.
