10 Steps to Build an Asian Brand,elevant economic variables and ε is the vector of unknown random errors. The most common method of estimating β. is the method of least squares: . argmin ε(β)′ε(β), where ε(β) ≡ Y - Xβ. Under fairly general assumptions . is an unbiased estimator of β. provided E(ε.|X) = 0 for all t, where ε. is the tth-coordinate of ε.

Errors in Variables,umns of . are zero vectors. In the conventional case the errors are uncorrelated in the limit with the latent values .* and the disturbances u; and the errors have zero means, constant variances, and zero autocorrelation. In observed variables the model becomes
