Right-hand side variables
Weball the right-hand-side variables are exogenous. But what happens if one of the right-hand-side variables is endogenous? I If all the Gauss-Markov assumptions are true except the one of exogeneity then the OLS estimators of the coefficients become biased, inconsistent and inefficient. Thus, we cannot apply the OLS to neither demand nor supply ... WebYou can use f_rhs function from the rlangpackage to extract the right handside of the formula and combine it with all.vars > f <- Species ~ Petal.Length + Petal.Width > > # RHS …

WebIf you just want the variable names, all.vars is a very helpful function: all.vars(f2[-2]) [1] "Petal.Length" "Petal.Width" The [-2] is used to exclude the left hand side. WebFeb 7, 2015 · Adding the slack-variables, we get the following problem. Max z = 2 x 1 − 6 x 2, s.t. − x 1 − x 2 − x 3 + w 1 = − 2 2 x 1 − x 2 + x 3 + w 2 = 1 x i, w j ≥ 0. First, a feasible solution must be found. Since the right-hand side is negative, we cannot simply choose x i = 0, since this would contradict w 1 ≥ 0.
