Consider the following unobserved or fixed effects model: Yit = B1Xit + a + Ut, t= 1, ..., T(1), where aj is the unobserved or fixed effect. Which of the following statements is correct? (See Examples 14.1 and 14.2.) An alternative method to first differencing to eliminate the fixed effect, a, is called the fixed effect " transformation. Vn=B,Xµ+Ü# , where ỹt , Xg andü r are the time-demeaned data on y, x and u, respectively, is the fixed effect b. transformation model of (1).

Pls help with below homework

Consider the following unobserved or fixed effects model: Yit = B1Xit + aj + Ut, t= 1, .., T(1), where aj is the unobserved or fixed effect. Which of the following statements is correct? (See Examples 14.1 and 14.2.) An alternative method to first differencing to eliminate the fixed effect, a, is called the fixed effect "transformation. Vn=B1X+üt, where ỹt , X andü are the time-demeaned data on y, x and u, respectively, is the fixed effect transformation model of (1). The time-demeaned data on y is ÿt=Yr-V¡ , where y;=T¯E;=¡YR . The time-demeaned data onx and u Oc. are defined similarly. O d. All of the above.
