The equation for a straight line (deterministic model) is
If the line passes through the point ( −2, 4), then x = −2, y = 4 must satisfy the equation; that is,
Similarly, if the line passes through the point (4, 6), then x = 4, y = 6 must satisfy the equation; that is,
Use these two equations to solve for β0 and β1 ; then find the equation of the line that passes through the points ( −2, 4) and (4, 6).

- Ye = C1 + C2x + Cze3* + C4xe3x Yp = Ax? + Bx +C Since C,x & Bx and C, & C are similar how do I use the modification rule so that the y, is linear independent?arrow_forwardYou want to find the determinants of suicide rates in Turkey. To investigate the issue, you specified the following model (i refers to region and t refers to year) Bo + B,X, + Regional Dummies + u, where Y, is the suicide rate and X, contains only the unemployment rate but no year dummies. Using OLS, you find no significant relationship between suicide rates and unemployment rate variable. Which of the followings can explain this result? Yanıtınız: There is no causal relationship between suicide rate and unemployment * There may be regional fixed effects, which are in the error term, that are correlated with unemployment rate Lack of interaction variables between regional dummies and unemployment rate Regional dummies are correlated with unemployment rate There may be year effects. which are in the error berm that are correlated with unemployment ratearrow_forwardBy eliminating the arbitrary constants of y = Cx² + C2x³ using determinants, then which of the following is the resulting D.E.? х?у" — 4ху' + бу %3D0 2x'y" – 3x?y' + 6y = 0 2x?у" - 2ху' — Зу%3D0 х?у" + 4ху' — 3у %3D0 O A B.arrow_forward
