“…3 Mandelbrot and Wallis (1969a) were the first to recognize R/S as non-parametric, even in presence of extreme skewness or with infinite variance. León and Vivas (2010), Martin et al (2003), Willinger et al (1999) and Peters (1996 and1994) verified such statement. 4 Moreover, since the purpose of this paper is not to establish the source of dependence, either short-term or long-term, but to detect and measure its impact in financial assets' returns long-run dynamic, Lo's (1991) criticism is rather irrelevant.…”

“…independencia -inclusive en presencia de dependencia de largo plazo-, lo cual se aprecia en la convergencia asintótica de Vq al límite superior del intervalo de confianza al 95%. Este comportamiento del estadístico Vq ha sido reconocido por varios autores (Martin et al, 2003;Willinger et al,1999;Teverosky et al,1999;Nawrocki, 1995), quienes señalan la importancia de escoger un número de rezagos (q) acorde con la dinámica de la serie de tiempo.…”

“…Otras debilidades de la metodología mR/S y de su prueba de hipótesis de independencia son el asumir que el proceso de la variable aleatoria es de tipo gaussiano (Mandelbrot, 2003;Martin et al, 2003;Brock et al, 1996), y que el intervalo de confianza es de naturaleza asintótica, lo cual supone que el tamaño de la muestra utilizada y el rezago tienden a infinito (Martin et al, 2003;Teverosky et al, 1999;Willinger et al,1999).…”
