Thanks Will. Below is the flow of my code Yhat is the fitted value Errhat is the difference between the dependent variable and the yhat gmmdata is the data name N <- nrow(gmmdata) B <- 1000 store <- matrix(0,B,11) for (j in 1:B) { index = sample(1:N, N, replace=T) errnew = errhat[index] yt = yhat + errnew objective function subroutine gradient function subroutine gmmiv =Optimx() store[j,] = coef(gmmiv) }
What I want to do is that if the convergence code from optimx for a particular iteration is Not zero, then it should not be stored in store[j,]. Any help will be appreciated Thank you -------------------------------------------- On Tue, 9/15/15, Will Hopper <wjhopper...@gmail.com> wrote: Subject: Re: [R] Drop in a Loop Cc: r-help@r-project.org Date: Tuesday, September 15, 2015, 2:30 PM I think you ought to show a small example of how the code you're using. Are you saving results at every iteration? In a list, data frame, etc? People likely need that to help answer your question. Also probably have a look the control list argument and the save.failures option, that might be something you're interested in. - Will On Tue, Sep 15, 2015 at 1:34 PM, Olu Ola via R-help <r-help@r-project.org> wrote: Hello, I am doing some estimation using optimx and after each round of estimation, I store the coefficient. However, I need to drop the set of coefficients for which the convergence code in optimx is GREATER than Zero. How do I go about this? A way forward will be highly appreciated.
