Algorithms for calculating variance play a major role in computational statistics. A key difficulty in the design of good algorithms for this problem is that formulas for the variance may involve sums of squares, which can lead to numerical instability as well as to arithmetic overflow when dealing with large values. (en) Los algoritmos para calcular la varianza juegan un papel importante en la . Una dificultad clave en el diseño de buenos algoritmos para este problema es que las fórmulas de la varianza pueden incluir sumas de cuadrados, lo que puede llevar a problemas de inestabilidad numérica así como a cuando se trata de valores grandes. (es) Gli algoritmi per il calcolo della varianza giocano un ruolo molto importante nella statistica computazionale. Una difficoltà chiave nel progetto di un buon algoritmo per questo problema è che le formule per la varianza possono includere somme di quadrati, che possono condurre a instabilità numerica così come overflow aritmetico quando vengono trattati grandi valori.
