Hi everyone, I have a question regarding the use of excel solver in maximizing a cell with three parameters. I am trying to solve a three parameter maximum likelihood in excel. However, every time I tried to solve it, excel said that the solver encountered an error value in the objective or constraint cell. But when I use the solver to maximize a two parameter maximum likelihood, there is no problem. Do you know how to solve this issue? Thank you for your help in advance and I would appreciate your help.
