I am trying to estiamte a system of nonlinear equations and I am new to Eviews but have programming background. I managed to import my data and create all the necessary variables and I defined my equation system thus:
When I try to estimate it, it says I don't have any valid observations in my system, which is puzzling to me. I have uploaded the working file. I am a bit unfamiliar with EViews as a work environment so I feel a bit lost.
Code:
param sigma .5 psi 1 alphal 0.05 alphae 0.01
ly = log(psi(1)) + sigma(1)/(sigma(1) -1) *log(kl*(exp(alphal(1)*beta*t)*(lbar^beta)*(kbar^(1-beta)))^((sigma(1) -1)/sigma(1))+(1-kl)*(exp(alphae(1)*t)*quality*ebar)^((sigma(1) -1)/sigma(1)))
les = (sigma(1) -1)/sigma(1) * (log(psi(1)) + log(quality)+alphae(1)*t)+ (1-sigma(1))/sigma(1) * ly + (1+sigma(1))*log(ebar) + log(1-kl)
lls = (sigma(1) -1)/sigma(1) * (log(psi(1)) + alphal(1)*beta*t + beta*log(lbar) + (1-beta) * log(kbar)) + (1-sigma(1))/sigma(1) * ly + log(kl*beta)
