Abstract: New invariants of measures, called the $ \beta$-statentropy, are described. They are similar to the entropy and the $ HP$-spectrum for dimensions. The $ \beta$-statentropy admits construction of a statistical estimator calculated by $ n$ independent points distributed in accordance with a given measure. The accuracy of this estimator is $ \mathcal{O}(n^{-c})$, where $ c$ is some constant, and the complexity of calculation is $ \mathcal{O}(n^2)$.

It is shown that for an exact dimensional measure the 0-statentropy coincides with the Hausdorff dimension, and for a Markov measure the $ \beta$-statentropy coincides with the $ HP$-spectrum for dimensions.

An application of the $ \beta$-statentropy to finding the entropy and dimensional characteristics of dynamical systems is described.
