Hi there. this is my first time i use eviews and i want to represent an equation. i dont know how to modify the variables. the equation is
Ln y/L= Ln A+gt-(α+β)/(1-α-β) Ln(n+g+σ)+α/(1-α-β) Ln(sk)+β/(1-α-β) Ln(sh)
Please help me out in this case.

Can you write your equation again? It is broken.

More precisely, we aren't quite sure what everything you have written down is supposed to represent.

Hi friends. the original equation is
and I want to represent it as a log-linear form.
Y = the product, L = labor, A = the level of technology used, sk = the ratio of investment to product, sh = human capital investment, n, g, and δ = the growth rates of labor, technology, and capital amortization respectively, and t = time.

Assuming your growth rates and sigma are known.
Code: Select all
equation eq1.ls log(y/l) = log(a) + log(g*@trend) - (c(1)+c(2))/(1-c(1)-c(2))*log(n+g+sigma) + c(1)/(1-c(1)-c(2))*log(sk) + c(2)/(1-c(1)-c(2))*log(sh)
Otherwise put coefficients in for them.

Thanks for ur quick help, i appreciate that. would you please do the same method for this equation :
or simply breaking them down,

I can't think of an easy way to enforce the inequality conditions off of the top of my head.

No.
You may want to review the rules about logarithms.
