### Balanced category theory

Some aspects of basic category theory are developed in a finitely complete category $C$, endowed with two factorization systems which determine the same discrete objects

We show that a large subclass of variograms is closed under products and that some desirable stability properties, such as the product of special compositions,

We consider a nonparametric goodness of fit test problem for the drift coefficient of one-dimensional small diffusions. Our test is based on discrete observation of
