Community,
I am working with my colleague Kim on a project she used random forest to develop a prediction model for plant disease in potato based on soil properties. Here are our questions:
- How do we use new data with the already generated model that was already validated?
- How can we validate that the old predictive model is explaining the response variable?
The predictive model indicates that with higher iron you get higher disease pressure. We want to use data from a previous year and see if that holds true.
Thank you very much for your kind suggestions.
