Quantification is useful in scenarios of distribution shift. In other Quantification is useful in scenarios of prior probability shift. In other
words, we would not need to estimate the class prevalences of the test set if words, we would not be interested in estimating the class prevalences of the test set if
we could assume the IID assumption to hold, as this prevalence would simply coincide with the we could assume the IID assumption to hold, as this prevalence would simply coincide with the
class prevalence of the training set. That is to say, a Quantification model class prevalence of the training set. For this reason, any Quantification model
should be tested across samples characterized by different class prevalences. should be tested across samples characterized by different class prevalences.
