The Flow matrix is a novel method to describe and extrapolate transitions among categories. The Flow matrix extrapolates a constant transition size per unit of time on a time continuum with a maximum of one incident per observation during the extrapolation. The Flow matrix extrapolates linearly until the persistence of a category shrinks to zero. https://safeersappliancers.shop/product-category/bosch-serie-6-kin85afe0g-integrated-50-50-fridge-freezer/
