'Statistics to validate model with independent data set
I am working on modeling the understory forest using the RandomForest classifier. The results are the probability values of understory tree occurrence. And I have an independent dataset, which was not utilized in model building. I want to test how reliable the prediction model is against the field data.
I would like to know what statistics should I use to do it? I was thinking to use a t-test but I doubt it is good statistics. I wonder if I can use kappa statistics or agreement statistics but I am not so sure about it. I hope someone can help me with this. Thank you.
