Re: simultaneous equations involving?

I used your comment. I can run my model . Thanks alot I have a question about the rate variables: Is it possible to use a rate variable as a function of 2 or more the other variable? I have some rate variables that they have this characteristic but after running, only one of input variable value hav...

Re: simultaneous equations involving?

In my loop, there isn't a converge value and iterate to it. The simultaneous function ( SIMULTANEOUS(A,B)) is an iterative solution, but I want to order the variables. Of course, i used Simultaneous function in my loop, but the loop haven't been converged. As i mentioned you above, This is a real lo...

Re: simultaneous equations involving?

Hi,
I have a SD model. Because the nature of variables in my model, all of them are Auxiliary.
after running this model i see "Simultaneous equation involving". I send a picture of my loop.
Please help me in this matter.
