Hello everyone, I am looking for a solver program like the excel's solver. I need to find a rate that makes a difference equal to zero, is a cash flow with terminal value that needs to be equal to a number.
A program, an add-in or a command would be very appropiate.
Thanks a lot!
Karina
Is there a solver tool?

Re: Is there a solver tool?
Hi
I too failed to manage to use the command-line version of irrval. Tried both the global command, and the series version.
Irrval(series=«seriesname»)
Irrval(«seriesname»)
Irrval(seriesname)
(And with versions like scalar test = …. Any of the above).
Seriesname.irrval(results)
Since the menu -alternative is working I guess all that is needed is an update of documentation.

Hello,
Take a look at EViews' optimize command, which is the general purpose command for user-defined optimization. It requires knowledge of EViews programming to use, but it's very flexible once understood.

Yes, the problem is due to output argument. Use "result" instead of "results" when calling the add-in from the command line and it should be fine. Please let me know if the problem persists.

Each add-in comes with the help file, where author explains its use in detail. You can find the document in the add-in's folder-> C:\Users\...\Documents\EViews Addins\irrval
