OLS Estimation of the AR(1) Model

[@anisha7975]

How to use instrument variable method to estimate the regression coefficient in first order autoregressive model???

[@abiperwira9605]

How to interpret AR(1) in multiple LS regression model (GDPt = INVt + CONt + GOVt + AR(1)? Could I say like this "GDP next year is significantly influenced by this year residual?

Is the estimator biased? How?

[@rasmuspedersen3195]

For a given number of observations, the expectation/mean of the estimator does not equal the true (population) value of \phi (in general). The estimator is asymptotically unbiased, that is, consistent (under suitable conditions).
