It is shown that mean and variance can be computed using only one dimensional numerical integration method. The speed of the proposed algorithms is compared with the baseline algorithm. Simulation results showed that the first proposed method decreases the execution time by an average of 43.98 %. Simulation results also showed that the second proposed method is faster than the first proposed method for the variances greater than 0.325.eninfo:eu-repo/semantics/openAccessArticle2701261111434437
