Evaluating your model side-by-side with a range of other models

Since Chap integrates a large number of models under a unified interface, it is easy to compare the predictions of your model against those of alternative models using a variety of input data, metrics and visualisations.

The most powerful way of comparing models is to install the Chap modelling platform alongside a DHIS2 instance, allowing you to run your and other models through the GUI of the “Modelling App”, which includes interactive side-by-side comparison of predictions by different model.

As a simpler setup, you can also evaluate your own and other models one by one using the Chap command line interface (the chap evaluate command), and then compare the resulting predictions in your preferred way. A range of existing models in the field has already been integrated with Chap, and can be run through the Modelling App or by using the following chap evaluate commands.
