Random matrix models is an efficient tool to study the Anderson metal-insulator transition. In this talk we focus on two such models: the power-law banded random matrices and the ultrametric random matrices. Using the weak disorder virial expansion we show how the multifractal critical exponents can be calculated analytically. Relations between different critical exponents, universality of the results as well as some open problems are discussed.
