%description
Gaussian mixture modeling of one- and two-dimensional data, provided in
original or binned form, with an option to estimate the number of model
components. The method uses Gaussian Mixture Models (GMM) with initial
parameters determined by a dynamic programming algorithm, leading to
stable and reproducible model fitting. For more details see Zyla, J.,
Szumala, K., Polanski, A., Polanska, J., & Marczyk, M. (2026)
