    Method of windowed correlation dimension estimates based on correlation dimension (D2) estimates by Grassberger–Procaccia algorithm is presented. Concept of generalization of correlation dimension DC) is demonstrated by softening the requirements of D2 estimation algorithm and by iterative approach to determine the optimal parameters of this algorithm. The whole modified method is thoroughly demonstrated on model data (2D grid of points and Lorenz attractor). This method is then applied, and generalized correlation dimension is calculated for thermal plasma dynamics in subsequent chunks of data. For noise-free data with clearly defined dimensionality, DC approaches correlation dimension D2.
