Suppose we have a binary classification problem. 99.8% of individuals in our sample = 0, 0.2% = 1. We downsample: we randomly sample say 1% of the individuals which =0, but keep all which =1. We fit our model to this new smaller sample, and now we have a model which produces probabilities that an individual = 1. How do we adjust our output probabilities to use this model on the population as a whole?
