TY - JOUR TI - The coefficient of variation asymptotic in case of non-iid random variables T2 - Journal of Applied Statistics VL - 36 IS - 1-2 AU - Curto, J. AU - Pinto, J. PY - 2009 SP - 21-32 SN - 0266-4763 DO - 10.1080/02664760802382491 AB - Due to the widespread use of the coefficient of variation in empirical finance, we derive its asymptotic sampling distribution in the case of non-iid random variables to deal with autocorrelation and/or conditional heteroskedasticity stylized facts of financial returns. We also propose statistical tests for the comparison of two coefficients of variation based on asymptotic normality and studentized time-series bootstrap. In an illustrative example, we analyze the monthly return volatility of six stock market indexes during the years 1990–2007. ER -
