Researchers have explored the use of Compactly Supported Radial Basis Functions (CS-RBFs) as a novel parametric family for probability density functions, particularly focusing on Wendland $\mathscr{C}^2$ kernels. The study provides analytical expressions for statistical properties like moments and cumulative distribution functions in both univariate and conditional settings, considering scenarios with truncated and untruncated support. An incremental learning algorithm is also introduced for density estimation using CS-RBF mixture models, demonstrating competitive performance against Gaussian Mixture Models on synthetic and real-world datasets.
