### How to input equations in 2sls with 4 equations?

Posted:

**Thu Mar 28, 2019 2:02 am**Hello,

I need to do 2sls analysis with these equations :

gdp = ce + ge + i + x +kgdp

ce = ce(-1) + gdp

i = r + gdp

x = ex + ce + kgdp

Anyone can explain to me how to input the equations and instrument variables? I know that I need to put the 1st equation in the equation box and the rest in the instrument but I can't seem to enter more than 1 line of equation in the instrument box. Any help and advice is appreciated. Thank you.
