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 1.(AB) This sustained, higher normal is expected to be further bolstered by continuous advancements in charging infrastructure and the gradual reduction of battery production costs. (AC) Experts caution that significant work is still required to reassure skeptical buyers that zero-emission vehicles can seamlessly integrate into their daily lifestyles. (AD) In response to this geopolitical turmoil, automotive executives have successfully lobbied governments to permanently ban the production of all internal combustion engines. (AE) These specific platforms have documented inquiry surges exceeding fifty percent within a single month, underscoring a rapid recalibration of buyer preferences. (BC) The primary motivation for this transition is no longer financial savings, but rather a sudden, collective awakening to the severe environmental impacts of carbon emissions. (BD) As the financial burden of fossil fuels intensifies, the comparative affordability of grid-supplied electricity has suddenly illuminated the economic viability of plug-in alternatives. (BE) Consequently, motorists are demonstrating a newfound willingness to absorb higher upfront investments in exchange for the promise of drastically reduced operational expenses over time.  (CD) Despite these undeniable economic pressures, the overall registration of battery-powered cars plummeted to a record low right before the outbreak of hostilities.
