Estimators of long range dependence : a survey of finite samples and robustness
- Mathematics
- 2012
In traditional financial theory the returns of prices are assumed to be independent of each other, they are said to have short memory. However, it has been shown that returns in many cases are…
Rescaled Range Analysis and Detrended Fluctuation Analysis: Finite Sample Properties and Confidence Intervals
- Mathematics
- 2010
We focus on finite sample properties of two mostly used methods of Hurst exponent H estimation—rescaled range analysis (R/S) and detrended fluctuation analysis (DFA). Even though both methods have…
R/S analysis and DFA: finite sample properties and confidence intervals
- Mathematics
- 2009
We focus on finite sample properties of two mostly used methods of Hurst exponent H estimation – R/S analysis and DFA. Even though both methods have been widely applied on different types of…
Long-range dependence in returns and volatility of Central European Stock Indices
- Economics
- 2010
In the paper, we research on the presence of long-range dependence in returns and volatility of Hungarian (BUX), Czech (PX) and Polish (WIG) stock indices between years 1997 and 2009 with a use of…

The Effect of the Underlying Distribution in Hurst Exponent Estimation

It is shown that, under this model, no stocks from S&P500 index show persistent memory, whereas some of them do present anti-persistent memory and most of them present no memory at all.

THE ESTIMATION AND APPLICATION OF LONG MEMORY TIME SERIES MODELS
- Mathematics
- 1983
Abstract. The definitions of fractional Gaussian noise and integrated (or fractionally differenced) series are generalized, and it is shown that the two concepts are equivalent. A new estimator of…
Long-Term Memory in Stock Market Prices
- Economics
- 1989
A test for long-run memory that is robust to short-range dependence is developed. It is a simple extension of Mandelbrot's "range over standard deviation" or R/S statistic, for which the relevant…
Long-term stochastic dependence in financial prices: evidence from the German stock market
- Economics
- 1996
A number of authors have argued that financial prices may exhibit hidden long-term dependence. We consider this claim analysing German stock market data. Applying three different concepts for the…
Stock market prices and long-range dependence
- EconomicsFinance Stochastics
- 1999
Using the CRSP (Center for Research in Security Prices) daily stock return data, the question of whether or not actual stock market prices exhibit long-range dependence is revisited and empirical evidence of long- range dependence in stock price returns is found but the evidence is not absolutely conclusive.
Long Memory in Stock-Market Trading Volume
- Economics
- 2000
This article examines consistent estimation of the long-memory parameters of stock-market trading volume and volatility. The analysis is carried out in the frequency domain by tapering the data…
Scaling in financial prices: I. Tails and dependence
- Economics
- 2001
The scaling properties of financial prices raise many questions. To provide background - appropriately so in the first issue of a new journal! - this paper, part I (sections 1 to 3), is largely a…
Robustness of the rescaled range R/S in the measurement of noncyclic long run statistical dependence
- Mathematics
- 1969
The rescaled range R(t, s) / S(t, s) is shown by extensive computer simulation to be a very robust statistic for testing the presence of noncyclic long run statistical dependence in records and, in…
Real and Spurious Long-Memory Properties of Stock-Market Data
- Economics
- 1996
We test for the presence of long memory in daily stock returns and their squares using a robust semiparametric procedure of Lobato and Robinson. Spurious results can be produced by nonstationarity…
What color are commodity prices? A fractal analysis
- Economics
- 2000
Abstract. Commodity price behavior holds much interest not only because these markets are affected by waves of speculative activity similar to security markets but more so that these commodities are…
